S.C.R. No. 9 is a Senate Concurrent Resolution from the State of Texas that emphasizes the importance of an independent U.S. Supreme Court as a vital component of the nation's system of checks and balances, which safeguards constitutional rights. The resolution notes 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 would undermine the court's independence.

The resolution calls on the U.S. Congress to propose the "Keep Nine" amendment to the Constitution, which would formally establish that the Supreme Court shall consist of nine justices. It also 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 included in the Congressional Record. The resolution was adopted by both the Texas Senate and House, reflecting significant legislative support for maintaining the current structure of the Supreme Court.
