Question:

How long must a Jammer wait to yield advantage in the case of a false start? If the opposing Jammer chooses not to take the advantage, is either Jammer awarded a penalty?

Answer:

Once the Jammer receives her false start minor penalty and is told to yield, she must stop all forward motion until the opposing Jammer takes the lead by passing her. The Jammer who false-starts may not position her body in a way so as to impede the opposing Jammer’s forward or lateral motion. Once the Jammer passes the false start Jammer, both Jammers resume normal play.  In the case where a false-starting Jammer yields her advantage but the opposing Jammer does not take advantage of that yielding, neither Jammer will be awarded an additional penalty.

Question:

If a player is not permitted to join a jam because she was not in position at its start, is she then allowed to join a Jammerless Jam that follows?

Answer:

No, such a player was not on the track in the previous jam, and so cannot be a part of the Jammerless Jam that follows.  The following rules logically extend to Blockers:

6.4.5.3 During a Jammerless jam, when one or both Jammers fail to be on the track when the jam starts, both teams will play a Jammer in the new jam.
6.4.5.3.1 No substitutions will take place.  The team(s) must skate short, however they are permitted to field a Jammer from one of the Blockers that played in the stopped jam.

Question:

Both scoring referees award and signal Lead Jammer status to their Jammers (the second, mistakenly). If the second Jammer successfully calls off the jam (incorrectly believing she is the Lead Jammer), should she be assessed a penalty?

Answer:

No. It is only a penalty for a Jammer who is NOT Lead Jammer to call off a jam (6.2.8). If both Jammers are awarded Lead Jammer status, even in error, then an appropriate use of referee discretion (8.3.1) should be to dismiss any penalty assessment.
