Section 148.05 - Mandatory indemnification(1) A medical society shall indemnify a director or officer, to the extent he or she has been successful on the merits or otherwise in the defense of a proceeding, for all reasonable expenses incurred in the proceeding if the director or officer was a party because he or she is a director or officer of the medical society.(2)(a) In cases not included under sub. (1), a medical society shall indemnify a director or officer against liability incurred by the director or officer in a proceeding to which the director or officer was a party because he or she is a director or officer of the medical society, unless liability was incurred because the director or officer breached or failed to perform a duty he or she owes to the medical society and the breach or failure to perform constitutes any of the following: 1. A willful failure to deal fairly with the medical society or its members in connection with a matter in which the director or officer has a material conflict of interest.2. A violation of criminal law, unless the director or officer had reasonable cause to believe his or her conduct was lawful or no reasonable cause to believe his or her conduct was unlawful.3. A transaction from which the director or officer derived an improper personal profit.(b) Determination of whether indemnification is required under this subsection shall be made under s. 148.06.(c) The termination of a proceeding by judgment, order, settlement or conviction, or upon a plea of no contest or an equivalent plea, does not, by itself, create a presumption that indemnification of the director or officer is not required under this subsection.(3) A director or officer who seeks indemnification shall make a written request to the medical society.(4)(a) Indemnification under this section is not required to the extent limited by the medical society's constitution or bylaws under s. 148.09.(b) Indemnification under this section is not required if the director or officer has previously received indemnification or allowance of expenses from any person, including the medical society, in connection with the same proceeding.
