Yellow 33 drives to basket when a contact occurs. The referee calls a personal foul on Black 2 and makes the decision that Yellow 33 had already started his act of shooting. Article 47.3 When deciding on a personal contact or violation, the referees shall, in each instance, have regard for the following fundamental principles: Consistency in application of advantage/disadvantage. The referees should not seek to interrupt the flow of the game unnecessarily in order to penalise incidental personal contact which does not give the player responsible an advantage nor place his opponent at a disadvantage Outcome: Incorrect decision from the referees. Regarding basketball knowledge and the principle of advantage/disadvantage, the contact created by Black 2 doesn't have any effect on the dribbler's freedom of movement, speed, balance or quickness and no foul should have been called.
