Nor do I remember. I tried a cursory

of Guide 62. Couldnt locate any. If you find it please update me.
You need to defend if you are called upon by the court to defend. Unfortunately I have some legal background in the family. The legal system in India is also modelled on the British system. The court will simply throw out any claim against the CB for violating "accreditation criteria" as "not under jurisdiction". Just the same way you as a QMS auditor would not bother about a safety issue "not related to product".
The issue is not violation of the contract. The issue is relating to the violation of Guide 62 - which is neither a criminal nor a civil law. I wonder under what jurisdiction you might put it.
