The bill aims to address illegal immigration by amending section 907.041 of the Florida Statutes, specifically regarding pretrial detention and release. It establishes a presumption that no conditions of release will ensure the appearance at trial of an unauthorized alien. If a court finds probable cause that a defendant committed an offense and determines, by a preponderance of the evidence, that the defendant is an unauthorized alien, the state attorney or the court must move for pretrial detention. Defendants are given the opportunity to rebut this presumption by demonstrating that adequate conditions of release can secure their appearance at trial.

Additionally, the bill includes a severability clause, ensuring that if any part of the act is deemed invalid, the remaining provisions will still be enforceable. The changes to the law will take effect upon the bill becoming law.
