Article I, Section 20 of the Texas Constitution ("Outlawry or Transportation out of State for Offense")
As amended November 5, 1985:
No citizen shall be outlawed. No person shall be transported out of the State for any offense committed within the same. This section does not prohibit an agreement with another state providing for the confinement of inmates of this State in the penal or correctional facilities of that state.
As adopted in 1876, this section read: "No citizen shall be outlawed, nor shall any person be transported out of the State for any offence [sic] committed within the same."
It has been amended once. The 1985 amendment expressly authorized interstate agreements for the confinement of Texas inmates in correctional facilities in other states.
- Robin v. Ely & Walker Dry Goods Co., 137 S.W.2d 164, 167 (Tex.Civ.App.–Austin 1940, ref'd) ("The Texas constitutional provision that 'no citizen shall be outlawed, nor shall any person be transported out of the State for any offence committed within the [State],' has reference only to an offense against the constitution or laws of this State. This provision  could not control the government of the United States in the enforcement of its penal laws, because as above pointed out, its laws and jurisdiction under the provisions of Clause 2, Art. 6 of the United States constitution are superior to the laws of this State with respect to the matter of bankruptcy laws.")
