The Commission meets annually to review member activities over the past year and for the next year, to review compliance and conservation measures and to review existing regulatory measures. Important decisions are made by consensus in CCAMLR and become legally binding in international law on members after 180 days should no objections be lodged. Working groups are also convened for important issues, for example the ad hoc Working Group on the Incidental Mortality Arising from Longline fishing (WG-IMAF).
