Legal Task Group

The FSSB’s Legal Task Group is primarily comprised of at least one member from each OSAC subcommittee to provide a legal perspective for the subcommittee. Task group members are selected based on their experience in litigating, judging, legal counseling, teaching or writing about forensic science evidence in the legal system. The group is available for consulting with the FSSB and all OSAC subcommittees on legal and legally related issues. Task group members work together to gather and submit their comments on standards, technical publications, definitions, and other OSAC and FSSB documents, with an emphasis on their legal impacts and on the presentation of forensic science results within the legal system.
