to reduce or eliminate their ability to understand exactly what they are doing, such conditions are self-induced and so the law does not generally allow any defense or excuse to be raised to any actions taken while incapacitated. The most generous states do permit individuals to repudiate agreements as soon as sober, but the conditions to exercising this right are strict. Business entities General and limited partnerships There is a clear division between the approach of states to the definition of partnerships. One group of states treats general and limited partnerships as aggregate. In terms of capacity, this means that they are no more than the sum of the natural persons who conduct the business. The other group of states allows partnerships to have a separate legal personality which changes the capacity of the "firm" and those who conduct its business and makes such partnerships more like corporations. Juridical persons Corporations The extent of an juridical person's capacity depends on the law of the place of incorporation and the enabling provisions included in the constitutive documents of incorporation. The general rule is that anything not included in the corporation's capacity, whether expressly or by implication, is ultra vires, i.e. "beyond the power" of the corporation, and so may be unenforceable by the corporation, but the rights and interests of innocent third parties dealing with the corporations are usually protected. Trade unions In some states, trade unions have limited capacity unless any contract made relates to union activities. Insolvent business entities When a business entity becomes insolvent, an administrator, receiver, or other similar legal functionary may be appointed to determine whether the entity shall continue to trade or be sold so that the creditors may receive all or a proportion of the money owing to them. During this time, the capacity of the entity is limited so that its liabilities are not increased unreasonably and to the detriment of the existing creditors.
