Contractus civiles

In Roman law. Civil contracts. Those contracts which were recognized as actionable by the strict civil law of Rome, or as being founded upon a particular statute, as distinguished from those which could not be enforced in the courts except by the aid of the prætor, who, through his equitable powers, gave an action upon them. The latter were called "contractus prœtorii." Contractus est quasi actns coutra actum.

2 Coke, 15.

A contract is, as it were, act against act Contractus ex turpi causa, vel coutra bonos mores, nullus est. A contract founded on a base consideration, or against good morals, is null.

Hob. 167.
