(11)The legally binding requirements applicable to CCPs authorised in India therefore comprise a two-tiered structure. The core principles which RCCs and authorised clearing houses must comply with in order to obtain authorisation to provide clearing services in India (‘the primary rules’) are the following: (a) under the SEBI regime, the core principles for RCCs set out in the SCRA and the Regulations complemented by the Circular of 4 September 2013 which requires compliance with the PFMIs and (b) under the RBI regime, the PSSA and the PSS Regulations, together with the Policy Document for Regulation and Supervision of Financial Market Infrastructures, which requires compliance with the PFMIs. Those primary rules comprise the first tier of the legally binding requirements in India. In order to prove compliance with the primary rules, RCCs have to submit their internal rules and procedures to SEBI for approval. Under the RBI regime, authorised clearing houses have to comply with their internal rules and procedures in the operation of their authorised clearing houses. Those internal rules and procedures comprise the second tier of the legally binding requirements in India, which must provide prescriptive detail regarding the way in which RCCs and authorised clearing houses will meet those standards. Moreover, the internal rules and procedures of RCCs and authorised clearing houses contain additional provisions which complement the primary rules in certain aspects. The internal rules and procedures of RCCs and authorised clearing houses, which implement the PFMIs, are legally binding upon RCCs and authorised clearing houses.
