Additional Civil Judge of Kadi taluka H J Tanna let off Patel and two others by giving them the benefit of doubt as the prosecution failed to provide any substantial evidence to back their case.
Along with Patel, who handles the Health portfolio among others, two BJP leaders of Kadi - Lalji Patel and Arvind Kapadia - were also booked for alleged breach of model code of conduct in November 2007.
At that time, Gujarat Congress had complained to the election authorities that Nitin Patel and others violated the poll code by making derogatory remarks about the party and its leaders.
Based on the complaint, Kadi mamlatdar (a taluka-level government officer) lodged an FIR against the trio.
Absolving them in the case, the court said the prosecution failed to provide any substantial evidence like video recording of the speech.
