Last December, Texas lawmakers passed Senate Bill 4, one of the most extreme pieces of anti-immigrant legislation to emerge from any state legislature. Under S.B. 4, local and state law enforcement can arrest people they suspect to have entered Texas without federal authorization. It also permits Texas judges, who are not trained in immigration law, to order the deportation of migrants to ports of entry along the Texas-Mexico border, regardless of which country they are from. Additionally, individuals may face charges under a new state crime of “illegal entry,” or “illegal re-entry,” as well as refusal to comply with deportation orders, with some charges carrying penalties of up to 20 years in prison. Since S.B. 4 passed, a whirlwind of court orders have stopped it from being enforced or allowed it for a very short time, which has caused widespread confusion. States do not have the constitutional authority to deport people, and an unconstitutional law like S.B. 4 only imposes added threat to migrants’ livelihoods and path to asylum.  Here to give us the latest news on S.B. 4 and our fight against it is David Donatti, senior staff attorney at the ACLU of Texas working on immigration.
