Sumathi ran quite a few interesting posts on the grant of GI to Tirupati Laddu. In the last post, a regular reader of the blog and a scientist from Kerala, Mr.Praveen Raj, posted in his comment that he had written a letter to the Hon'ble Chief Justice of India K.G.Balakrishnan against the grant of the GI, further requesting that the letter be treated as a writ petition.
We now have information that a PIL has been filed before the Madras HC on similar lines by one Mr.Mohanraj, a retired Police Officer and the General Secretary of Jebamani Janata Party (JJP). The PIL contests the grant of a trademark to the image of the presiding deity of the Attukal Temple and the grant of GI to Tirupati Laddu; a stay over the grant of both rights has been prayed for.
