The courts prevent such circuitous actions, for it is a maxim of law, so to judge of contracts as to prevent a multiplicity of actions; and in the case just put, they would hold that the covenant not to sue operated as a release. 1 T. R. 441. It is a favorite object of courts of equity to prevent a multiplicity of actions. 4 Cowen, 682.
