Title 13, Chapter 1, Section 7
(a) A contract may be absolute or conditional. In an absolute
contract, every covenant is independent and the breach of one does
not relieve the obligation of another. In a conditional contract,
the covenants are dependent upon each other and the breach of one is
a release of the binding force of all dependent covenants.
(b) The classification of every contract must depend upon a rational
interpretation of the intention of the parties.
