What this article means

The principles of interpretation in the Rules of Court also govern the construction of contracts.

Rule 123 of the Rules of Court referenced here contained the rules of evidence, including principles on how extrinsic proof may be weighed against the words of a written document. By cross-referencing that rule, this article makes clear that contract interpretation is not governed by the Civil Code's canons alone; the evidentiary framework that limits or permits proof of a party's true intent operates alongside them, so a court construing an ambiguous contract draws on both bodies of rules together rather than treating them as separate exercises.
