The Constitution forbids caps
Article 10, section 4(a) of the Wyoming Constitution bars any law limiting the amount of damages recovered for injury or death. Fault is governed by W.S. 1-1-109, which allows recovery at 50% or less and makes each defendant liable only for its share.
Claims against governmental entities follow the same Title 1 statutes: W.S. 1-39-118 limits recovery, and the general deadline is four years under W.S. 1-3-105.
