Legal immunity from suit or liability (in civil litigation) or immunity from prosecution (in criminal prosecutions) is a legal status that protects an individual or entity from liability or criminal prosecution. Immunity may be given to the person or entity by law (usually a state or federal statute) or by the agreement of a party to the litigation (usually in the context of a criminal prosecution)—generally for some greater policy goal. Some common types of immunity include (1) judicial immunity; (2) witness immunity; (3) diplomatic immunity; and (4) governmental or sovereign immunity.

In Wyoming, legal immunity from suit or liability in civil litigation and from prosecution in criminal cases is recognized in various forms. Judicial immunity in Wyoming protects judges from being sued for their judicial acts, provided those acts are within their jurisdiction and performed in a judicial capacity. Witness immunity is granted to individuals who testify in court, ensuring they cannot be sued for their testimony. Diplomatic immunity, which is governed by federal law and international treaties, shields foreign diplomats from civil and criminal jurisdiction in the U.S., including Wyoming. Governmental or sovereign immunity generally protects the state of Wyoming and its political subdivisions from being sued without their consent, although this immunity can be waived in certain circumstances, such as through the Wyoming Governmental Claims Act. This Act allows for certain types of lawsuits against the state or its employees for acts performed within the scope of their employment, subject to limitations and exceptions. It's important to note that the specifics of how these immunities apply can vary based on the context and the particular laws or agreements in place.
