<P> Since 1789 , Congress has occasionally altered the size of the Supreme Court , historically in response to the country 's own expansion in size . An 1801 act would have decreased the Court 's size to five members upon its next vacancy . However , an 1802 act negated the effects of the 1801 act upon the Court before any such vacancy occurred , maintaining the Court 's size at six members . Later legislation increased its size to seven members in 1807 , to nine in 1837 , and to ten in 1863 . An 1866 act was to have reduced the Court 's size from ten members to seven upon its next three vacancies , and two vacancies did occur during this period . However , before a third vacancy occurred , the Judiciary Act of 1869 intervened , restoring the Court 's size to nine members , where it has remained since . </P>
