House Bill 521 establishes that individuals convicted of a crime who sustain injuries or damages while committing that crime will not have the right to seek damages, provided that the victim involved did not use any force or only used justifiable force as defined in Title 45, chapter 3, part 1. This legal change aims to clarify the circumstances under which a convicted person can pursue legal action for injuries incurred during their criminal activities.

The bill includes a codification instruction indicating that this new provision will be integrated into Title 27, chapter 1, part 5 of the Montana Code. This integration ensures that the new law is treated as a part of the existing legal framework governing actions for damages.
