 An example is the Privy Council decision in "Attorney General of the Cayman Islands v Wahr-Hansen", where the Council held that gifts to "organisations or institutions operating for the public good" and acting "for the good or for the benefit of mankind" failed, because the definition given was not exclusively charitable.There are two exceptions to the rule of exclusivity; ancillary purposes, and severance.Where the non-charitable purpose is a necessary ancillary to the charitable one, the trust will not fail.
