A Texas immigration law, one of the nation's toughest ever, has been temporarily frozen by an appeals court. The law would empower officials to detain and prosecute individuals they suspect of entering the country illegally, overriding federal authority. Although the law briefly took effect during legal manoeuvres, a three-judge panel heard arguments on its constitutionality without issuing an immediate ruling. The Justice Department requested a delayed effective date if the law were to be upheld, intending to seek emergency action from the Supreme Court. Joe Biden's administration opposed the law, on the grounds that immigrant detention should remain in its hands. Mexico denounced the law as anti-immigrant, pledging not to accept individuals deported by Texas. The law’s potential reinstatement could signify a significant departure in immigration enforcement, challenging the traditional federal authority. Crossing the US border illegally is already a federal crime, but violations are usually handled as civil cases by the immigration courts.
