No, India does not view things exactly the same way the west does re: the rule of law vs. institutional power. The regulator has broad authority to stop market manipulation and support from the public that we do not want HFT style manipulation skimming money from everyone else in our markets. SEBI does not need to wait for a precisely worded law for every single type of market manipulation that will take years to pass and then be sidestepped in months on some technicality. They stopped bad activity quickly only because they have some actual power to make judgements and enforce them.
