Dera Sacha Sauda chief Gurmeet Ram Rahim Singh on Monday filed an application before Central Bureau of Investigation (CBI) special court, Haryana, for more writing samples of one of the rape victims so that a disputed letter, which is a part of his defence, could be evaluated for handwriting matching.
The CBI has been asked to file a reply by April 27 and the same day the arguments will take place.
"This is again a frivolous application. These are his (Ram Rahim) delaying tactics," said CBI counsel HPS Verma.
Ram Rahim is facing trial for allegedly raping two women.
The Chandigarh-based Central Forensic Science Laboratory (CFSL) had informed the CBI court on Saturday that the handwriting evaluation results remained inconclusive as there was not sufficient material to ascertain the author of the letter.
Ram Rahim claims that one of the rape victims had written the letter on her last day at the dera and forms an important part of his defence evidence. The letter addresses dera chief as "Pitaji", extols him and does not have any mention of rape allegations.
In 2002, anonymous letters were circulated about sexual exploitation of sadhvis at dera sacha sauda following which the CBI registered the case on the orders of the high court. Both the prosecution and defence evidence have been closed in the case.
