The Catholic faithful decides, at times with the instructions he receives from his bishop, at other times by his own informed conscience; a Catholic has an obligation to work on properly forming his conscience at all times.

Jeremiah 17:9 9 The heart is deceitful above all things and beyond cure. Who can understand it?
John 16:7-8 7 But I tell you the truth: It is for your good that I am going away. Unless I go away, the Counselor will not come to you; but if I go, I will send him to you. 8 When he comes, he will convict the world of guilt in regard to sin and righteousness and judgment:
John 2:24-25 24 But Jesus would not entrust himself to them, for he knew all men. 25 He did not need man’s testimony about man, for he knew what was in a man.
Man's heart is corrupt and deceitful and is not to be trusted in matters of conscience. It's up to the Holy Spirit to take care of matters like that.
