How judges apply the law to specific disputes may depend in their personal philosophical views?

No, it does not depend upon the whim and caprice of the judges, nor it depends upon his personal philosophical view. The strong reason is that he is a judge and not a philosopher. Both the fields are different.

A judge should clearly realize his position as a judge. A judge, with whom the confidence is reposed by the people of any Country, is not free alike individual in the society. A judge has to adore the Constitution, the existing principles of law and the precedent.
