In U.S. constitutional law, when a court finds that a law infringes a fundamental constitutional right, it may apply the strict scrutiny standard to nevertheless hold the law or policy constitutionally valid if the government can demonstrate in court that the law or regulation is necessary to achieve a "compelling state interest". The government must also demonstrate that the law is "narrowly tailored" to achieve the compelling purpose, and uses the "least restrictive means" to achieve the purpose. Failure to show these conditions may result in a judge striking down a law as unconstitutional.
