A Texas court temporarily blocks SB4 law, which made irregular border crossings a state crime. The judicial decision is based, among other reasons, on the lack of jurisdiction of the state authorities to take the Government's own immigration measures.

Parts of the law went into effect on February 6, specifically the one that establishes that a mandatory minimum sentence of 10 years will be imposed on those accused of trafficking undocumented immigrants. If the crime is considered serious, the minimum prison sentence amounts to 15 years or more if there is another legal provision that is applicable.
