Civil court jurisdiction barred: suits and injunctions precluded where statutory adjudicatory mechanisms have exclusive competence. No civil court shall entertain any suit or proceeding in respect of any matter which an adjudicating officer or a Securities Appellate Tribunal is empowered by the Act to determine, and no injunction shall be granted by any court or other authority in respect of any action taken or to be taken in pursuance of any power conferred by the Act.
