When the matter is already entrusted to Advocate, unnecessary worry and interference may strain relations between client and advocate. Trust your advocate and let him do the professional thing without doubting his competency.
It's a Petition and not Complaint by the Defendant. Obviouslt it must be Criminal Miscrllaneous Petition.
Complaint can only be filed by the Court which is rare. Your premature panic is unwarranted.
Courts are slow to act in such cases. Every lie of the Witness is not taken by courts seriously. And I support this because mostly these are inadvertant and not dishonest.
Nevertheless confirm yourself that your witnesses are true.
