What is the ambit of judicial activism today?

Its 'wide' enough. As you know, the root for this is PIL(public interest litigation) where the court of law is saught for redressal of issues that have been unheard/unattended to/subjected to callousness of other wings of democracy like executive and legislature. Of late 'judicial activism' (ja)is being looked at as anathema to the legislative and executive as the judiciary is lambasting the callousness of legislative/executive. It is unbecoming that stalwart Mr.somnath chaterjee even is now against 'ja' and heavily endorsing supremacy of parliament only. But one can see that judiciary is the last resort for the oppressed and depressed one with the help of which he or she can bring the bull of politics by its horns. Incidentally, certain politicians ,but cleverly, are now disturbing the bees nest in various 'sensitive' issues like reservations, endowments posing as 'Messiahs' dedicated for the cause, but infact they want the issues to be pended by the courts and now the courts ought to take up such matters unfortunately and whatsoever they say they are subjected to be taken out the mileage required by the parties by saying either that 'they are bound by the Hon'ble courts' or 'the judiciary is going excess under 'ja'. This is pathetic. Be that as it may, I personally feel that we should thank the 'ja' without which there will not be responsible governments.
