Article 224 - Equity
Canon 2773 (link)
In the adjudication of agreement disputes, the principle of Equity is to consider the merits and facts of the dispute without regard to the implicit higher or lower claims of ownership. Hence, by treating both parties as equal, the principle of equity necessarily seeks to invoke a form of justice of the law.
Canon 2775 (link)
Decisions of Equity do not make the law, but assist in its proper interpretation.
