Can a GK shake the goal post

My team recently played against a team where the GK would shake the goal post everytime our shooters would take a shot. She was not picked up for this at all, i believe it was an infringment, maybe intimidation or some type of contact. Can someone advise, is this a viable play, or is it an infringment. It was very obvious, she would only shake the goal post once the shooters had released the ball for a shot, not before so she wasnt leaning on it for support and she kept doing it and was never picked up

A player may not use the goalpost in anyway. Whether or not the shooter has released the shot, you are not allowed to use the goalpost for support, or any other reason (including shaking). The umpire should of called the GK for 'using the goalpost' and your team should have been awarded with a penalty pass or shot, with the GK to stand beside and away.

I agree with Claire.  if you see something a player is doing continually, and it isn't being picked up, you should go and ask or bring it to the attention of the umpire.  particularly if the umpire is not seeing it.  what that player was doing was simply poor sportsmanship, and her coach should have pulled her up for it too.  unless she was taught to do it.

No way, and any umpire that lets that go should give up their whistle, that's just plain bad sportsmanship and completely against the rules. 

Hi Nalini, rule 15.3 applies, it reads as follows%3A A defending player may not cause the goalpost to move so as to interfere with the shot at goal.

The penalty is pass or shot to opposing team to be taken%3A -

(i) from where the infringer was standing unless this places the non-offending team at a disadvantage;

(ii) if the infringer was out of court, on coart near the point where the infringer was standing.
