7. One who is known to consistently commit a certain sin whose prohibition is known to all, and he is not careful of this sin whatsoever, it is permitted to condemn him both in his presence as well as in his absence, under the following conditions: The speaker has himself seen him commit the sin. 2. It is obvious to him that it is actually a sin. 3. He does not exaggerate the act. 4. His intention is for a constructive purpose. 5. He must not flatter him in his presence, and condemn him behind his back. However, if he has disregarded all the commandments these conditions are not necessary.
8. One who does not follow through on a rabbinical court order, for seemingly no good reason, it is permitted to speak badly about him. If he has a good reason, but we are doubtful of its truth, we are forbidden to speak badly about him.
