Yes, a grand jury indictment is a constitutional right for serious federal crimes under the Fifth Amendment but not a universal right for all state crimes, as the Supreme Court ruled it's not "incorporated" to apply to states, though many states still use them. It protects citizens from unfounded federal prosecutions by requiring a grand jury to find probable cause before a "capital, or otherwise infamous crime" goes to trial.

Can a judge overrule a grand jury indictment?

Yes, but it's very rare and only for specific, serious reasons like prosecutorial misconduct or constitutional violations, not simply disagreeing with the grand jury's finding of probable cause; a judge can't overrule an indictment based on the sufficiency of the evidence, as that's the grand jury's role, but might dismiss it if the process itself was fundamentally flawed.

Is Amendment 7 still 20 dollars?

Yes, the Seventh Amendment's "$20" threshold for federal civil jury trials technically still exists in the Constitution, but it's functionally ignored due to inflation, meaning it doesn't really apply to modern cases; it applies to federal civil cases, not state ones, and the real minimum for federal court jurisdiction is now much higher (often $75,000). The $20 back in 1791 was significant, but today it's tiny, so courts focus on larger disputes, effectively making the $20 clause obsolete in practice, though it hasn't been formally removed.
