You seem to be reading "upon receipt" as meaning "at the moment of receipt". But, that's not what the law states. In my opinion "upon receipt of said notice" means that they simply cannot schedule you for a hearing BEFORE they receive your notice. The rule does NOT state a time frame. For example, in WA, the court rule states:
But, even with THAT specification, if you don't receive the notice within 21 days, it's still NOT grounds for dismissal.Quoting IRLJ 2.6 (a)
