The proposed bill establishes new legal provisions regarding unauthorized aliens in Florida, creating Chapter 811 of the Florida Statutes, which includes sections 811.101, 811.102, and 811.103. It defines key terms such as "removal" and "unauthorized alien," and outlines criminal penalties for unauthorized aliens who illegally enter or attempt to enter the state after evading immigration inspection. The bill mandates minimum imprisonment terms for such offenses, with enhanced penalties for repeat offenders. It also specifies that unauthorized aliens cannot be arrested under certain circumstances, provides affirmative defenses, and requires courts to presume that no conditions of release can ensure their presence at trial, leading to mandatory detention.

Additionally, the bill stipulates that unauthorized aliens who have been previously denied admission or deported and subsequently re-enter the state will face felony charges, with mandatory minimum sentences based on prior convictions. It further prohibits these individuals from eligibility for civil citations or diversion programs and mandates that law enforcement agencies notify relevant authorities upon the arrest of an unauthorized alien. Lastly, the bill includes a provision that requires a death sentence for unauthorized aliens convicted of capital felonies, reinforcing the stringent legal framework surrounding immigration enforcement in Florida.
