IIHF:n säännöissä estäminen menee näin:
534 - INTERFERENCE
a) A player who interferes or impedes the progress of an opponent who is not in possession
of the puck shall be assessed a:
Minor penalty (2’)
b) A player on either the players bench or the penalty bench who, by means of his stick
or his body, interferes with the movement of the puck of any opponent on the ice
during the progress of the play, shall be assessed a:
Minor penalty (2’)
c) A player who, by means of his stick or his body, interferes with or impedes the progress
of the goalkeeper while he is in his goal crease, shall be assessed a:
Minor penalty (2’)
d) If, when the goalkeeper has been removed from the ice, any member of his team,
including a team official interferes by means of his stick or any other object or his
body with the movement of the puck by an opposing player outside his own defending
zone, the Referee shall award to the non-offending team a:
Goal
e) If an attacking player positions himself facing the opposing goalkeeper and engages
in actions such as waving his arms or stick in front of the goalkeeper's face for the
purpose of interfering and/or distracting the goalkeeper as opposed to positioning
himself to try to make a play, regardless whether the attacking player is positioned
inside or outside of the goal crease, the Referee shall assess a:
Minor penalty
NHL:n säännöissä menee näin (kakkosten lisäksi):
56.4 Major Penalty - The Referee, at his discretion, may assess a major penalty, based on the degree of violence, to a player guilty of interfering with an opponent (see 56.5).
56.5 Game Misconduct Penalty – When a major penalty is imposed under this rule for a foul resulting in an injury of an opponent, a game misconduct shall be imposed.
Käsittääkseni SM-liigalla ei ole muutoksia IIHF:n sääntöihin estämisen osalta.
