Question: Can you engage the jammer in a no pack situation?
Answer: In No Pack situations blockers may not actively or passively engage a Jammer ... Or other blockers. This includes, but not limited to, hitting, booty blocking or merely standing in her way -- These are all penalties in no pack situations. Likewise, jammers may not engage blockers in a No Pack situation, as they are considered out of play -- jammers are still subject to penalties for an action to an Out of Play player. A Jammer can however engage the other jammer as long as both players remain In Play (on the track, upright).
Question: Who's responsible for reforming the pack in a No Pack situation?
Answer: The onus is on both teams to try and reform the pack, however only one person is required to attempt to reform the pack.

If one team attempts to reform the pack, and the other team attempts to evade or keep the pack destroyed, then the offending team will be assessed the penalty.
