Section 6 of the Medical Termination of Pregnancy Act, 1971 is the quiet engine room of the whole statute. The substantive entitlements live in Sections 3 and 5, but the practical conditions under which a pregnancy may lawfully be terminated, the categories of women who qualify, the gestational thresholds and the composition and functions of the Medical Board are all settled by rules the Central Government makes under Section 6. The 2021 amendment turned this once-modest housekeeping provision into the constitutional fault line of the entire Act, because the most litigated phrase in modern reproductive-rights jurisprudence, Rule 3B of the MTP Rules, 2003, is delegated legislation framed under this very section. This chapter examines the text of Section 6, its companion Section 7 on State regulations, the doctrine of delegated legislation that governs both, and the landmark decision in X v. Principal Secretary, Health and Family Welfare Department that read the rules down to save them from unconstitutionality.
The text and scheme of Section 6
Section 6(1) is a classic general rule-making clause: "The Central Government may, by notification in the Official Gazette, make rules to carry out the provisions of this Act." Section 6(2) then particularises, opening with the standard formula that the enumeration is "without prejudice to the generality of the foregoing power". As originally enacted, clause (a) authorised rules on the experience or training a registered medical practitioner must possess if he intends to terminate a pregnancy, and a residuary clause (b) covered such other matters as may be prescribed. Section 6(3) subjects every rule to the laying procedure before both Houses of Parliament for thirty days, with a modification-or-annulment power, the familiar device of negative parliamentary control.
The architecture is deliberate. Parliament fixed the policy, the grounds for termination, the persons who may perform it, the gestational ceiling, in the parent Act, and left the technical and administrative detail to the executive. This is the textbook relationship between primary and subordinate legislation. To understand why so much turns on a single rule, one must read Section 6 alongside the conditions in when a pregnancy may be terminated and the gestational scheme discussed in length of pregnancy and conditions, because Section 3 repeatedly defers to matters "as may be prescribed by rules made under this Act".
The drafting of Section 6(2) repays close reading. The opening words, "In particular, and without prejudice to the generality of the foregoing power, such rules may provide for all or any of the following matters", make clear that the enumerated clauses do not exhaust or cut down the general power in Section 6(1); they merely illustrate it. This is the standard interpretive device by which a particular enumeration following a general grant is read as additive rather than restrictive, so that the Central Government retains a residuary competence to make rules on any matter genuinely incidental to carrying out the Act. The original residuary clause (b), preserving the power to prescribe "such other matters as are required to be or may be provided by rules", reinforces that the list in Section 6(2) is open-textured. At the same time, the generality is not unlimited: a rule must still be one that genuinely carries out the provisions of the Act, and cannot become a vehicle for substantive policy that the statute itself does not authorise.
How the 2021 Amendment expanded Section 6(2)
The Medical Termination of Pregnancy (Amendment) Act, 2021 (Act No. 8 of 2021), which received Presidential assent on 25 March 2021 and was brought into force on 24 September 2021, substantially widened the rule-making mandate. Section 5 of the Amendment Act inserted three new clauses into Section 6(2) after clause (a): clause (aa) on "the category of woman under clause (b) of sub-section (2) of section 3"; clause (ab) on "the norms for the registered medical practitioner whose opinion is required for termination of pregnancy at different gestational age under sub-section (2A) of section 3"; and clause (ac) on "the powers and functions of the Medical Board under sub-section (2C) of section 3".
This is significant. By the amendment, Parliament took three of the most consequential matters in the new scheme, who qualifies for the 20-to-24-week window, what medical qualifications are needed at different gestational stages, and how the Medical Board operates for terminations beyond 24 weeks in cases of substantial foetal abnormality, and routed them through delegated legislation rather than spelling them out in the statute. The categories of women in the extended window are dealt with substantively in termination where pregnancy is caused by rape or contraceptive failure, but their precise enumeration is found only in the Rules.
The MTP Rules, 2003 and the 2021 overhaul
The principal subordinate instrument under Section 6 is the Medical Termination of Pregnancy Rules, 2003, which replaced the earlier 1975 Rules. The 2003 Rules prescribe the training and experience qualifying a practitioner, the manner of forming and certifying opinions, the forms in which terminations are recorded, and the safe custody of records. They were comprehensively recast by the Medical Termination of Pregnancy (Amendment) Rules, 2021 to give effect to the amended Act.
The 2021 Rules inserted, among others, Rule 3B, which lists the categories of women eligible to terminate a pregnancy of up to twenty-four weeks under Section 3(2)(b): survivors of sexual assault or rape or incest; minors; women whose marital status changes during the pregnancy (widowhood and divorce); women with physical disabilities; mentally ill women; cases of substantial foetal malformation; and women in disaster or emergency situations as declared by Government. The Rules also created Rule 3C on the constitution of the State or Union Territory Medical Board, mirroring the membership specified in Section 3(2D). Because these matters define the very reach of the right to terminate, the Rules are not mere administrative gloss, they carry the operative legal content the parent Act delegates to them.
Section 7: the State Government's power to make regulations
Section 6 must be read with its companion, Section 7, which confers a parallel but distinct power on the State Government to make regulations. Section 7(1) empowers the State Government to require that the opinion under Section 3(2) be certified by the registered medical practitioner concerned in such form and at such time as the regulations specify, to provide for preservation and disposal of such certificates [clause (a)], to require intimation of a termination and related information [clause (b)], and to prohibit disclosure of such intimation or information except to specified persons for specified purposes [clause (c)]. Section 7(2) directs that intimation and information under clause (b) be furnished to the Chief Medical Officer of the State.
The confidentiality mandate in clause (c) is the statutory anchor for the privacy protection now reinforced by Section 5A, inserted by the 2021 Amendment, which criminalises revealing the name and particulars of a woman whose pregnancy has been terminated. A wilful contravention of a regulation made under Section 7(1) attracts a fine up to one thousand rupees. The division of labour, Central Government rules under Section 6, State Government regulations under Section 7, reflects the concurrent character of public health and the need for both uniform national standards and locally administered reporting.
Rules versus regulations: a distinction that matters
Aspirants frequently conflate the MTP "Rules" with the MTP "Regulations", but the statute keeps them separate. Rules under Section 6 are made by the Central Government and concern the substantive machinery, practitioner qualifications, eligible categories, Medical Board functions. Regulations under Section 7 are made by the State Government and concern the procedural and reporting layer, certification of opinions, intimation, custody and confidentiality of records.
The Medical Termination of Pregnancy Regulations, 2003 thus operate at the State level and prescribe the forms, including the consent and opinion forms and the admission register, used in approved institutions. A second distinction lies in parliamentary control: Section 6(3) requires Central rules to be laid before each House of Parliament, whereas Section 7 requires State regulations to be laid before the State Legislature. The penalty clause attaches only to regulations under Section 7, not to rules under Section 6, a point worth remembering in objective examinations. The interaction with definitions such as "registered medical practitioner" is developed in definitions: pregnancy and registered medical practitioner.
The constitutional foundation: delegated legislation
Both Sections 6 and 7 are exercises in delegated legislation, and the validity of any rule or regulation made under them is governed by settled constitutional doctrine. The foundational authority is In re Delhi Laws Act, 1912, AIR 1951 SC 332, the seven-judge Special Reference in which the Supreme Court held that while the legislature may delegate the power to fill in details, it cannot abdicate its essential legislative function, the laying down of policy and standards. So long as the parent statute supplies the legislative policy, the executive may be entrusted with the subordinate task of working out the particulars.
Section 6 satisfies this test: the MTP Act lays down the policy, who may terminate, on what grounds, within what gestational ceiling, and delegates only the elaboration of categories, qualifications and Board functions. The amendment did not hand the executive an open-ended discretion; each new clause in Section 6(2) is tethered to a specific sub-section of Section 3. This careful tethering is what keeps the delegation within constitutional bounds and distinguishes a permissible filling-in of detail from an impermissible surrender of the law-making power.
The ultra vires control: rules cannot travel beyond the Act
The cardinal limit on any rule made under Section 6 is that it must conform to, and cannot exceed, the parent Act. In Kunj Behari Lal Butail v. State of Himachal Pradesh, (2000) 3 SCC 40, the Supreme Court held that a general delegation to make rules "for carrying out the purposes of the Act" cannot be exercised so as to create substantive rights, obligations or disabilities not contemplated by the Act itself; a rule travelling beyond the statute is ultra vires and void. The proviso impugned in that case was struck down for precisely this reason.
The grounds for challenging delegated legislation were synthesised in Indian Express Newspapers (Bombay) Pvt. Ltd. v. Union of India, (1985) 1 SCC 641, where the Court held that subordinate legislation may be questioned on the grounds that it does not conform to the parent statute, that it is contrary to some other statute, or that it is so manifestly arbitrary as to offend Article 14. These principles apply directly to the MTP Rules: a rule under Section 6 that purported, for instance, to narrow the grounds in Section 3 or to add disqualifications absent from the Act would be liable to be struck down as travelling beyond the delegated power.
Does laying before Parliament validate a defective rule?
Section 6(3) prescribes the laying procedure, but a recurring examination favourite is whether parliamentary laying cures a rule that is otherwise ultra vires. The answer, settled long ago, is no. In Hukam Chand v. Union of India, (1972) 2 SCC 601, the Supreme Court held that the requirement of laying rules before each House of Parliament does not confer validity on a rule that is not in conformity with the parent Act; the courts retain full power to scrutinise such rules and strike them down if they exceed the rule-making authority.
The laying procedure is therefore a mechanism of political accountability, not a constitutional cure. It allows Parliament to modify or annul a rule, but the absence of any such annulment does not immunise an invalid rule from judicial review. For the MTP Rules this means that even though the 2021 Rules were duly laid, their conformity with the Act remained fully justiciable, as the litigation over Rule 3B was soon to demonstrate.
X v. Principal Secretary: reading down a rule to save it
The most important modern decision on the MTP Rules is X v. Principal Secretary, Health and Family Welfare Department, Government of NCT of Delhi, (2023) 9 SCC 433 (decided 29 September 2022; also reported as 2022 SCC OnLine SC 1321). An unmarried woman sought to terminate a pregnancy of about 22 to 24 weeks arising from a consensual relationship that ended when her partner declined to marry her. Rule 3B(c) of the MTP Rules, 2003, as amended in 2021, listed among the eligible categories women whose marital status changed during the pregnancy, illustrated parenthetically as "widowhood and divorce".
Read literally, the rule excluded unmarried women in consensual relationships, and the High Court had declined relief. The Supreme Court held that such a narrow reading would render the rule discriminatory and constitutionally suspect under Article 14, observing that there was no rationale for confining the benefit of Rule 3B to married women. Adopting a purposive interpretation, the Court read the expression "change of marital status" expansively to include a change in the woman's relationship status, thereby extending the 20-to-24-week window to unmarried and single women facing a material change in circumstances. The Court treated the post-2021 scheme as making no distinction between married and unmarried women.
The reasoning bears directly on the law of delegated legislation. The Court observed that Rule 3B is subordinate legislation framed under Section 6, and that the rule-making power could not be construed to defeat the object of the parent Act, which the 2021 amendment had broadened to recognise the autonomy of all women. To exclude unmarried women would create an artificial distinction with no nexus to the purpose of the Act and would expose the rule to invalidity under Article 14. The Court also held that the statutory term "woman" in Sections 3 and 5, and correspondingly in the Rules, includes persons other than cisgender women, reading the scheme in a manner consistent with constitutional values. The judgment is thus a leading example of how the interpretive obligation to harmonise delegated legislation with the parent Act and the Constitution operates in practice, rather than the cruder remedy of invalidation.
Why the Court read the rule down rather than struck it down
The technique in X v. Principal Secretary illustrates a crucial point about delegated legislation. Faced with a rule capable of an unconstitutional narrow meaning, the Court did not strike Rule 3B(c) down; it adopted the construction that preserved its validity, the doctrine that where a provision admits of two readings, the one consistent with the Constitution is preferred. This is reading down in its classic form.
The decision also demonstrates the constitutional gravity that Section 6 rules can acquire. Because Parliament chose to place the eligible categories in delegated legislation rather than the statute, the question of who may access a late-term termination became a question of rule interpretation, decided by reference to Article 21 reproductive autonomy and Article 14 equality. The Court anchored the woman's right to make reproductive choices in the dignity and autonomy guaranteed by Article 21, building on the foundation laid in Suchita Srivastava v. Chandigarh Administration, (2009) 9 SCC 1, where it had first held that a woman's right to make reproductive choices is a dimension of her personal liberty under Article 21. The introductory framing of these rights appears in introduction, object and reproductive rights.
Rules governing the Medical Board
Clause (ac) of Section 6(2) and Section 3(2C) together delegate to the Central Government the task of prescribing the powers and functions of the Medical Board, the body each State and Union Territory must constitute to decide on terminations beyond twenty-four weeks where a substantial foetal abnormality is diagnosed. Section 3(2D) fixes the Board's minimum composition, a gynaecologist, a paediatrician, a radiologist or sonologist, and such other members as the State Government may notify, while the operative procedure is left to the Rules.
The MTP Rules, 2021 accordingly specify how the Board examines the woman and her reports and the timeline within which it must render its opinion. This is delegated legislation at its most consequential, for the Board's decision is dispositive in the highest-gestation cases. Yet because the Board's mandate derives entirely from rules under Section 6, its functioning too remains subject to the conformity and reasonableness controls in Kunj Behari Lal Butail and Indian Express Newspapers. The treatment of vulnerable women before the Board connects to the discussion in termination of pregnancy of a minor or mentally ill person.
The Medical Board mechanism also illustrates an important constraint on delegated power: the rules may regulate how the Board functions, but they cannot enlarge or curtail the statutory ground on which it acts. Section 3(2B) confines the Board's role to terminations necessitated by the diagnosis of substantial foetal abnormality, and no rule framed under clause (ac) could lawfully extend the Board's remit to other grounds or impose conditions that defeat a woman's entitlement under Section 3. In several post-2022 proceedings the Supreme Court and High Courts have emphasised that the Board's opinion must be reasoned, time-bound and respectful of the woman's autonomy, and that courts may direct constitution of a fresh Board where the statutory composition is not met, underscoring that the Board derives its legitimacy from, and remains confined by, the parent Act and the Rules made under Section 6.
Practical and examination significance
For judiciary and CLAT-PG candidates, Section 6 is deceptively rich. It is simultaneously a provision of the MTP Act and a vehicle for the entire doctrine of delegated legislation. A complete answer should identify the source of the power (Central Government, by Official Gazette notification), the matters delegated (practitioner qualifications, eligible categories under Section 3(2)(b), norms under Section 3(2A), and Medical Board functions under Section 3(2C)), the laying control in Section 6(3), and the distinction from State regulations under Section 7.
The case law must then be layered on: In re Delhi Laws Act for the permissibility of delegation, Kunj Behari Lal Butail and Indian Express Newspapers for the ultra vires and arbitrariness controls, Hukam Chand for the limited effect of laying, and above all X v. Principal Secretary for the reading-down of Rule 3B and the constitutional dimension of the Rules. A candidate who can move fluently from the statutory text to the doctrine and finally to the 2022 reading-down has mastered both the provision and the larger administrative-law lesson it carries. For the full statutory map, see the MTP Act notes hub.
Summary
Section 6 empowers the Central Government to make rules carrying out the Act, with Section 6(2) now expanded by the 2021 Amendment to cover eligible categories, gestational-stage norms and Medical Board functions, all subject to the laying procedure in Section 6(3). Section 7 confers a separate power on State Governments to make regulations on certification, intimation and confidentiality, enforced by a modest fine. The validity of every rule and regulation is governed by the law of delegated legislation: delegation of detail is permissible (In re Delhi Laws Act), but a rule may not travel beyond the Act (Kunj Behari Lal Butail), may be struck down for non-conformity or manifest arbitrariness (Indian Express Newspapers), and is not saved merely by being laid before Parliament (Hukam Chand). The decision in X v. Principal Secretary shows the practical stakes, reading Rule 3B of the MTP Rules expansively to extend late-term termination access to unmarried women and confirming that, under this Act, the rule-book carries constitutional weight.
Frequently asked questions
Who has the power to make rules under the MTP Act, 1971?
The Central Government, under Section 6(1), may by notification in the Official Gazette make rules to carry out the provisions of the Act. This is distinct from Section 7, under which the State Government makes regulations on certification, intimation and confidentiality.
What did the 2021 Amendment add to Section 6?
Section 5 of the Medical Termination of Pregnancy (Amendment) Act, 2021 inserted clauses (aa), (ab) and (ac) into Section 6(2), delegating to the Central Government the power to prescribe the categories of women under Section 3(2)(b), the norms for practitioners at different gestational ages under Section 3(2A), and the powers and functions of the Medical Board under Section 3(2C).
Why is Rule 3B of the MTP Rules so important?
Rule 3B, framed under Section 6, lists the categories of women eligible to terminate a pregnancy of up to 24 weeks. In X v. Principal Secretary, Health and Family Welfare Department, (2023) 9 SCC 433, the Supreme Court read "change of marital status" in Rule 3B(c) purposively to include unmarried women, extending the 20-to-24-week window to single women and avoiding discrimination under Article 14.
Can a rule made under Section 6 be challenged in court?
Yes. As delegated legislation it can be struck down if it travels beyond the parent Act (Kunj Behari Lal Butail v. State of H.P., (2000) 3 SCC 40), conflicts with another statute, or is so manifestly arbitrary as to violate Article 14 (Indian Express Newspapers v. Union of India, (1985) 1 SCC 641).
Does laying a rule before Parliament make it valid even if it is ultra vires?
No. In Hukam Chand v. Union of India, (1972) 2 SCC 601, the Supreme Court held that the laying procedure does not confer validity on a rule that is not in conformity with the parent Act; courts retain full power to scrutinise and strike down such a rule.
What is the difference between rules under Section 6 and regulations under Section 7?
Rules under Section 6 are made by the Central Government and cover the substantive machinery, such as practitioner qualifications, eligible categories and Medical Board functions, and are laid before Parliament. Regulations under Section 7 are made by the State Government, cover certification, intimation and confidentiality, are laid before the State Legislature, and carry a penalty of a fine up to one thousand rupees for wilful contravention.
