Situation 3

This is a case where possession and control by Team A is established by the Goalkeeper holding the puck.  Play is blown dead and the delayed penalty is assessed.  No additional "Delay of Game" penalty should be called on the goalkeeper.

Rule 612 Situation 1 is where the answer can be found. 

The Referee has signaled a penalty on player A1. The puck goes behind the Team A goal line and the Team A goalkeeper falls on the puck behind the goal line with his body entirely outside of the goal crease. Should he receive a penalty?

No. Rule References 612(b) and 409(b) Note 2. The Referee will stop play to assess A1’s penalty as soon as Team A gains possession and control of the puck.  The goalkeeper is allowed to hold the puck for three seconds before being assessed a penalty.  In this situation no penalty would be assessed to the goalkeeper since possession and control will occur before three seconds have elapsed.
