(a) In an action maintained by an association pursuant to subdivision (b), (c), or (d) of Section 1368.3, the amount of damages recovered by the association shall be reduced by the amount of damages allocated to the association or its managing agents in direct proportion to their percentage of fault based upon principles of comparative fault. The comparative fault of the association or its managing agents may be raised by way of defense, but shall not be the basis for a cross-action or separate action against the association or its managing agents for contribution or implied indemnity, where the only damage was sustained by the association or its members. It is the intent of the Legislature in enacting this subdivision to require that comparative fault be pleaded as an affirmative defense, rather than a separate cause of action, where the only damage was sustained by the association or its members.
(b) In an action involving damages described in subdivision (b), (c), or (d) of Section 1368.3, the defendant or cross-defendant may allege and prove the comparative fault of the association or its managing agents as a setoff to the liability of the defendant or cross-defendant even if the association is not a party to the litigation or is no longer a party whether by reason of settlement, dismissal, or otherwise.
(c) Subdivisions (a) and (b) apply to actions commenced on or after January 1, 1993.
(d) Nothing in this section affects a person's liability under Section 1431, or the liability of the association or its managing agent for an act or omission which causes damages to another.
