What does objective expression mean in law?

In practical work, the relationship between matter and consciousness is objective and subjective. In order to effectively transform the objective world in practice and make practice successful, we must deal with the relationship between subjective and objective, persist in proceeding from reality, make the subjective conform to the objective and the thought conform to the reality. The so-called reality is an objective fact. We should decide our principles, policies, plans, working methods and other subjective things according to objective facts. On the contrary, if we don't try to be consistent between subjectivity and objectivity in our work, but start from subjectivity and cut objectivity with subjectivity, it will inevitably violate the objective law and lead to the failure of practice.
