Madigan has until midnight, the 8th, to file for an en banc rehearing. The 7th circuit has 10 days to decide to rehear the case, or not.
If the case is not reheard, the clock is still ticking on any possible petition of cert to the SCOTUS.
If the case is to be reheard, the clock stops. That clock will be reset and won't start again until the decision of the en banc rehearing.
My personal opinion? Judge Posner is very, very respected within the 7th Circuit and unless there is some glaring error, I don't expect the court to grant the rehearing. That leaves Madigan with about 65 days to decide if she will file a petition for certiorari.
