What does the 26th Amendment have to do with the US Supreme Court?

Answer 1

The Twenty-sixth Amendment was passed in response to the US Supreme Court's decision in Oregon v. Mitchell, 400 US 112 (1970), where the court declared a section of the 1970 amendment to the Voting Rights Act of 1965 unconstitutional.

The Twenty-sixth Amendment simply lowers the voting age from 21 to 18 by constitutional means because the Court held the federal government couldn't dictate voting regulations to states by legislation. The Amendment was ratified by the states on July 5, 1971, and has not been challenged.

This is a regulatory Amendment that isn't amenable to special uses or limitations, except those that apply to voter eligibility, in general.
