Crpc 156(3) and then crpc 200

My sister's divorce case is on going in family court. But my brother in law filed complaint against my family under CrPC 156(3) in July 2023. I was not aware of this. We have not received any summons. Later magistrate rejected the complaint under 156(3) stating that it would be matrimonial dispute and directed case under CrPC 200 as private complaint in August 2024. My brother in law knows that case is fake and not attending from last 2 months. I have few questions: 1. Why we have not received any summons for section 156(3) or for private complaint 2. As respondent, do I have right to visit court and to be heard? 3. Currently my future employer is doing my background verification for criminal record and they found this case. Does it make me criminal? How to tell them that it is matrimonial dispute and complaint will be dismissed in few months 4. For private complaint, if complainant is absent then does court dismissed the complaint? 5. Does CrPC 156(3) means I have official complaint/case/FIR against me?
