S.C.R. No. 9 is a Senate Concurrent Resolution from the Texas Legislature that emphasizes the importance of an independent U.S. Supreme Court as a vital component of the checks and balances system that safeguards constitutional rights. The resolution highlights that the Supreme Court has traditionally been composed of nine justices for over 150 years and expresses concern that any attempts by the president or Congress to alter this number could undermine the court's independence.

The resolution calls on the U.S. Congress to propose and submit a "Keep Nine" amendment to the Constitution, which would formally establish that the Supreme Court shall consist of nine justices. Additionally, it mandates that the Texas Secretary of State send official copies of the resolution to key federal officials, including the president and congressional leaders, with a request for it to be recorded in the Congressional Record. The resolution was adopted by both the Texas Senate and House with significant support.
