The author of famous Potter series J K Rowling has filed a copyright violation case in the Delhi High Court against a Kolkata-based Durga pooja organiser for using statues of the Harry Potter characters without permission.

Justice Sanjay Kishan Kaul issued notice to the pooja committee and sought its reply by October 12, the day pooja begins.

The lawsuit sought a restraint order from the court against the pooja committee at Salt Lake from using Harry Potter characters on the pandal, as it was a clear violation of Rowling's intellectual property rights, the suit contended.

The pandal is designed in a manner which resembles Hogwarts Castle and displays statues of the Potter characters like Hagrid and Hedgewig apart from Potter himself, the suit said.
