(a) It is not sufficient on its face pursuant to the requirements of section 100.40; provided that such an instrument or count may not be dismissed as defective, but must instead be amended, where the defect or irregularity is of a kind that may be cured by amendment and where the people move to so amend; or
2. (b) The allegations demonstrate that the court does not have jurisdiction of the offense charged; or
