SDCL § 22-48-2.1: Claim of use of unreasonable force by victim--Hearing to determine reasonable basis for claim.

If the perpetrator claims that the victim used unreasonable force, before any discovery relating to the claim may be commenced and before the claim may be submitted to the trier of fact, the court, after hearing, must find, based on clear and convincing evidence, that there is a reasonable basis to believe that the victim used unreasonable force.
