Texas Tech University is in compliance with Comprehensive Standard 3.2.4.

Texas Tech University is a state related institution and the members of the Board of Regents are appointed by the state governor, subject to the approval of the state senate. (See Texas Education Code, 109.21 at http://www.capitol.state.tx.us/statutes/docs/ED/content/htm/ed.003.00.000109.00.htm). 

Regents are expected to operate independently of political, religious and other external influence. The Texas Education Code, Section 51.352. Responsibility of Governing Boards. Notes in Item #1 that the governing board of an institution of higher education in Texas “is expected to preserve institutional independence and to defend its right to manage its own affairs through its chosen administrators and employees”. (http://www.capitol.state.tx.us/statutes/docs/ED/content/htm/ed.003.00.000051.00.htm)

The university has no specific policy regarding a role for regents to protect the institution from outside influences.  However, there is no reason to doubt that they would comply with the law and support the chancellor and president in the event that undue external influence were brought to bear on the university.
