The question seems to be a misquoted statement from a judgment. The principle it refers to is that the 'test of reasonableness', which is a crucial standard for judging the validity of restrictions on Fundamental Rights (e.g., under Article 19), is an objective test. This means the court must determine whether the restriction is reasonable from the perspective of a rational and fair standard, considering factors like the nature of the right, the purpose of the restriction, and the extent of the infringement. It is not a 'subjective' test, which would depend on the personal opinion of the judge or the government. The constitution and judicial precedents provide the objective framework for this test.
