Procedures of the Supreme Court of the United States Thereafter, if the Court chooses to hold a hearing, each side has thirty minutes to present its case orally. In exceptional and controversial cases, however, the time limit may be extended.

The late Chief Justice Rehnquist was noted for his especially strict enforcement of the argument time limits.
