Article V sets no time limit for ratifying amendments, but Congress began attaching seven-year deadlines to proposed amendments in 1917. The Supreme Court affirmed Congress''s power to impose ratification deadlines in Dillon v. Gloss (1921). Congress passed the Equal Rights Amendment in 1972 with a seven-year deadline, then extended it to 1982 in a 1978 bill demonstrating Congress''s belief it can alter time limits. The 27th Amendment, ratified in 1992 after 203 years, shows amendments can succeed without deadlines. Chief Justice Charles Evans Hughes ruled in Coleman v. Miller that Congress has final authority on whether an amendment remains viable. Time limits appear in the proposing clause, not the amendment text itself. Nevada, Illinois, and Virginia ratified the ERA after its 1982 deadline expired, sparking debate over whether Congress can revive expired amendments or remove deadlines retroactively.
