At trial, an individual may “invoke the Fifth” by declining to testify in their own defense, and the prosecution may not comment on such a decision.
An individual can only invoke the Fifth Amendment in response to a communication that is compelled, such as through a subpoena or other legal process. The communication must also be testimonial in nature. In other words, it must relate to either express or implied assertions of fact or belief.
The Texas Constitution provides that the legislature, by a two-thirds vote of all members of each house, may propose amendments revising the constitution and that proposed amendments must then be submitted for approval to the qualified voters of the state.
