This discussion addresses how to convert a regular suit filed in Bombay High Court in 2015 into a commercial suit, particularly when it was registered as regular due to delayed court fee payment. While the Commercial Courts Act 2016 is generally prospective, an application under Section 15 can be filed to request the transfer of eligible commercial disputes to the commercial division. However, there's a differing opinion that suits filed before the Act's enactment should be adjudicated under existing laws, not retrospectively converted.
