The Seventh Guarantee of the Constitution of the United Federation of Planets protected all Federation citizens from being compelled to give self-incriminating testimony in legal proceedings.

In 2367, Simon Tarses invoked the Seventh Guarantee while being interrogated by Sabin Genestra and refused to discuss his Romulan heritage, having been so advised by his appointed counsel, William T. Riker. (TNG: "The Drumhead")

The Seventh Guarantee is analogous to the Fifth Amendment to the United States Constitution.
