IV. Who is covered

The Texas shield law defines the terms “journalist,” “news medium,” and “communication service provider.” See Tex. Civ. P. & Rem. Code §§22.021(1), (2), and (3) and Tex. Code Crim. Proc., art. 38.11, §§1(1), (2), and (3). The “journalist,” as defined in the statute, cannot be compelled to testify unless the tests set forth in the statute are met. Additionally, a subpoena may not compel a “communications service provider” or “news medium,” as defined by the statute, to disclose information unless the tests set forth in the statute are met. See Tex. Civ. Prac. & Rem. Code §22.023 and Tex. Code. Crim. Proc., art. 38.11, §3.
