The threshold in civil cases is balance of probability in criminal cases it's beyond reasonable doubt.
Most settlements in civil cases (out of court) are on the basis of no admission of liability, any settlement such as this action would normally have little or no bearing on any criminal cases.
I suspect in this instance the motion regards to expenses incurred when IIRC Rangers presented a motion in regards to certain documents then withdrew the motion after proceedings started, I'd be amazed if it was in relation to any settlement in the action against Charles green & others.
