An alternate member is permitted to vote in situations where the regular member is absent. This arrangement ensures that the IACUC can maintain quorum and effectively continue decision-making processes regarding animal research oversight. The presence of an alternate member allows for uninterrupted proceedings, thereby facilitating the necessary evaluations and approvals needed in IACUC functions.

The role of alternate members is pivotal in ensuring that meetings can progress without hindrance due to the absence of regular members, supporting the continuity and integrity of the review process. Other circumstances, such as voting to break ties or specific expertise scenarios, typically do not apply to the voting authority of alternate members as defined by IACUC protocols.
