Common law vs. statute

Both are rules of conduct proceeding from the supreme power of the state. That one is unwritten and the other written can make no difference in their validity or effect. The common law did not become a part of the laws of the states of its own vigor. It has been adopted by constitutional provision, by statute or decision... but, however adopted, it expresses the policy of the state for the time being only, and is subject to change by the power that adopted it.
