10.3.11 SITUATION A: After a field goal, A1 has the ball out of bounds for a throw-in. Thrower A1 holds the ball: (a) B2 crosses the boundary line and fouls A1; or (b) B2 reaches through the out-of-bounds plane and touches the ball while in the hands of A1. RULING: It is an intentional personal foul in (a), and a technical foul in (b). In (a), such a contact foul with the thrower during a throw-in shall be considered intentional, or if it is violent, it should be ruled flagrant. COMMENT: Either act is a foul and it should be called whenever it occurs during a game without regard to time or score or whether the team had or had not been warned for a delay-of-game situation. If the player making the throw-in (A1) reaches through the out-of-bounds plane into the court and B1 then slaps the ball from the hand of A1, no violation has occurred. B1 has merely slapped a live ball from the
hands of A1. (4-19-3, 4; 9-2-11 Penalty 3, 4)

Yep.
10.3.11 SITUATION C: Team A scores near the end of the fourth quarter and is trailing by one point. B1 has the ball and is moving along the end line to make the throw-in. A2 steps out of bounds and fouls B1. Is the foul personal or technical? RULING: This is an intentional personal foul. The time remaining to be played or whether Team A had been previously warned for a delay-of-game situation is not a factor. If the team had not been warned, the foul constitutes the warning. (4-19-1; 9-2-11 Penalty 4)

9.2.11 SITUATION: A1 is out of bounds for a throw-in. B1 reaches through the boundary plane and knocks the ball out of A1's hands. Team B has not been warned previously for a throw-in plane infraction. RULING: B1 is charged with a technical foul and it also results in the official having a team warning recorded and reported to the head coach. ...
