What would happen if the ERA was passed?

Quick overview: what an equal rights bill would mean

Why this question matters

An equal rights bill, if properly ratified and certified, would add a constitutional prohibition on discrimination “on account of sex” to the U.S. Constitution, creating a new textual guard against sex-based discrimination in law and government action, according to the National Archives National Archives.

What this article will cover

Readers should expect that the text alone would change constitutional law only after certification, and that its practical effects would depend on how courts and legislatures interpret and implement the new clause, as discussed by legal analysts and the Congressional Research Service CRS report.

The procedural status matters because Congress and courts have raised questions about certification, deadlines, and later state actions; these procedural issues affect whether and when the amendment takes effect, and they have been the subject of congressional resolutions in 2025 and 2026 Congress.gov.

This article breaks down the text, the process for ratification and certification, how courts are likely to approach the clause, likely areas of legal effect, legislative options to implement the change, common misunderstandings, plausible timelines, and reliable sources to follow.

What the equal rights bill would say in plain language

Text of the proposed amendment

The core language of the measure is short: it would add a provision that bars discrimination “on account of sex.” The National Archives publishes the amendment text and the formal steps for amendments, which shows the plain phrasing that would be added to the Constitution National Archives.

Key legal phrase: “on account of sex” and how courts treat it

Legal discussions emphasize that the simple phrase “on account of sex” is important because courts will use the clause as a starting point to determine standards of review and the scope of protection; the Congressional Research Service notes that judges will play a central role in defining what the clause covers CRS report.

In constitutional law, the level of judicial scrutiny determines how hard it is for a government or private actor to justify different treatment. Many commentators expect that courts would consider applying a heightened form of scrutiny to sex-based classifications once the amendment is part of the Constitution, though the precise doctrinal contours would develop over time and through case law Brennan Center analysis.

That means the text does not automatically prescribe exact outcomes. Instead, courts would interpret the new clause, decide how it overlaps with existing equal protection doctrine, and then apply those rules to disputes about employment, benefits, family law, and other areas of statute and regulation.

How ratification and certification would proceed for an equal rights bill

Ratification versus certification: who does what

The Constitution sets a process for amendments: an amendment must be proposed and then ratified by the legislatures of three quarters of the states, after which Congress typically directs the Archivist of the United States to certify the amendment for the public record, as described by the National Archives National Archives.

Recent congressional activity, including S.J.Res.38

Because some states acted at different times and some have attempted to rescind earlier ratifications, Congress has been asked to address whether the amendment can now be treated as part of the Constitution; in 2025 a joint resolution was introduced in Congress to treat the amendment as part of the Constitution, reflecting those unresolved certification questions Congress.gov and coverage in Ms. Magazine, and see the news page for related items.

State-level actions matter because ratification is reported by state legislatures to the Archivist, and later actions described as rescissions or updated reports create factual and legal questions about the count of ratifying states; the National Conference of State Legislatures explains varying state activity and reporting practices NCSL overview and the ERA FAQ ERA FAQ.

These procedural elements do not themselves decide the ultimate legal meaning of the clause, but they shape whether the Archivist and ultimately the courts will treat the amendment as properly part of the Constitution or whether Congress will take steps to resolve certification first.

How courts are likely to interpret the amendment

Standards of review and heightened scrutiny

Legal analysis from multiple sources anticipates that judges would examine the amendment’s text and likely consider applying heightened scrutiny to laws that classify on the basis of sex, which would raise the burden on governments to justify distinctions CRS report.

Procedural threshold questions courts must decide

Separate from doctrinal interpretation, courts are likely to see litigation over procedural issues such as whether rescissions by state legislatures count, how to treat ratification deadlines, and whether Congress must formally certify the amendment before courts apply it; these questions have been raised in recent litigation and legislative filings Congress.gov.

Where litigation is likely to go next

If those procedural disputes persist, legal challenges could proceed through district and appellate courts and may reach the Supreme Court to decide threshold issues about certification and timing, according to observers who track constitutional amendment procedure and relevant lawsuits CRS report.

Even after procedural questions are resolved, the courts would still shape the amendment’s application. Judges might clarify whether existing equal protection precedents change or whether the amendment supplements them, and that process could take several years of cases and appeals Brennan Center analysis.

Practical impacts: where an equal rights bill would change laws now

Employment law and workplace protections

Employment law is widely cited as an area likely to see immediate litigation because the amendment’s ban on discrimination on account of sex could alter how courts treat sex-based workplace rules and employer practices; civil-rights organizations note that employment protections and equal-pay claims would be prominent topics in early cases ACLU overview.

Which specific statutes and regulations change automatically is not a straightforward legal result. Instead, litigants would bring challenges under the new constitutional text and courts would decide whether particular statutory provisions remain permissible or need rewriting.

Family law, alimony, and child-related rules

Analysts identify family law as another central area for dispute, with potential challenges to sex-differentiated alimony rules, custody presumptions, or eligibility rules that treat men and women differently; observers expect litigation to test how family courts apply the new constitutional standard Brennan Center analysis.

Many family-law outcomes are determined by state statutes and court doctrines, so changes likely would appear in state-level litigation and legislative updates rather than instantaneous national uniformity; see our constitutional-rights hub.

Pensions, benefits, and sex-differentiated eligibility

Public benefits, pensions, and some pension-plan rules that use sex as a factor have been flagged as possible targets for constitutional challenge because the amendment would create a new textual bar to sex-based eligibility or benefit distinctions, according to civil-rights analyses ACLU overview.

Any successful constitutional challenge might require statutes or administrative rules to be revised to remove distinctions that a court deems inconsistent with the amendment, or Congress and state legislatures could pass clarifying implementing laws to reconcile existing frameworks.

What Congress and state legislatures would likely do next

Possible implementing statutes at the federal level

Congress has several tools: it could pass implementing statutes that clarify the amendment’s scope, set standards for enforcement, or address procedural certification questions before courts resolve them, and in 2025 Congress considered resolutions aimed at those certification issues Congress.gov; see our issues page for related discussion.

State-level reconciliation of statutes and rules

State legislatures would likely review statutes and administrative rules to identify provisions that rely on sex-based distinctions and decide whether to amend or defend those provisions, and groups that track state action provide overviews of where legislatures have considered such alignment NCSL overview.

Legislative options to clarify scope and timing

Legislatures could adopt narrowly tailored statutes to preserve certain programs while changing eligibility criteria, or they could wait for judicial rulings that set national doctrinal standards; CRS analysis suggests Congress might act to minimize uncertainty or to preserve policy choices within constitutional bounds CRS report.

Common misunderstandings and legal pitfalls about an equal rights bill

Mistaking certification for immediate legal change

One common misunderstanding is to treat certification as producing immediate, uniform legal outcomes across all areas of law. In practice, many effects will be worked out through litigation and legislation, so readers should not assume instant or automatic changes simply because the amendment is certified CRS report.

Assuming uniform outcomes across states

Another error is to assume that all states will experience the same timeline for change. State statutes, administrative practices, and litigation schedules differ, so the pace and pattern of legal change will vary across jurisdictions NCSL overview.

A third pitfall is overstating certainty about doctrinal results; commentators and scholars can map possibilities, but they attribute outcomes to likely judicial developments and legislative steps rather than treating them as settled law Brennan Center analysis.

Scenarios and a plausible timeline if the equal rights bill is certified

Scenario A: Congress resolves certification quickly

Under a faster path, Congress could pass a joint resolution or other implementing measure recognizing that a sufficient number of states ratified the amendment and directing the Archivist to certify it; that action would reduce some procedural uncertainty and allow courts to apply the new text more readily in pending cases Congress.gov and tracking on Legiscan.

Scenario B: Multi-year litigation reaching higher courts

Under a slower path, disputes about rescissions, deadlines, or the Archivist’s authority could lead to multi-year litigation that moves through district and appellate courts and could reach the Supreme Court for a final answer on threshold questions, as observed by legal analysts CRS report.

Key milestones to watch

Concrete milestones include official certification by the Archivist, congressional votes or implementing statutes, complaint filings in key litigation, appellate decisions about procedural thresholds, and eventual doctrinal rulings applying the amendment to specific statutes; tracking those items helps observers understand which scenario is unfolding National Archives.

Takeaways and reliable sources to follow

Short summary of key points

A certified equal rights bill would add a constitutional ban on discrimination on account of sex, but the amendment’s real-world effects depend on certification, court interpretation, and implementing legislation rather than occurring instantly upon certification CRS report.

Primary sources and monitoring checklist

To monitor developments, check primary sources and neutral trackers: the National Archives for the amendment text and certification records, Congress.gov for resolutions and votes, CRS reports for legal analysis, NCSL for state-level action, and reputable civil-rights groups for interpretive commentary National Archives.

Reporters, students, and voters benefit from observing whether Congress acts on certification, whether the Archivist issues a formal certification, and whether appellate courts accept or question that certification. Those events will shape the amendment’s path and timing.
