Can I be charged with resisting if the arrest was illegal?

This is one of the most counterintuitive rules in Florida criminal law, and getting it wrong has serious consequences.

Section 776.051 provides that a person is not justified in using force to resist an arrest by a law enforcement officer known to be an officer — even if the arrest is unlawful. The remedy for an unlawful arrest is in court, not at the scene.

So a person who physically resists an arrest that later turns out to have been improper can still face a resisting with violence charge, and the illegality of the arrest is not a defense to it.

The analysis differs for resisting *without* violence. There, the lawfulness of the officer's conduct bears on whether the officer was engaged in the lawful execution of a legal duty — an element the State must prove. An unlawful detention can defeat that charge.

The practical rule: comply, state clearly that you don't consent, and challenge it later. Physical resistance converts a suppressible problem into a new felony.
