SM Chopra, a former additional district judge who has been appointed as the local commissioner by the high court to record evidence on a day-to-day basis, has fixed August 21 and 21 as dates for the examination of Tiwari in the case.
The local commisioner, who has already concluded the examination of Rohit and his mother, had asked the leader to file his evidence by way of an affidavit.
The counsel for Tiwari had indicated that he may file an application before the court seeking an order to conduct his cross-examination outside Delhi.
The Congress leader has so far refused to settle the lawsuit out of court through mediation saying there was a possibility that even the medical evidence was not hundred percent accurate.
The high court had on July 27 last year read out the DNA report in the case as per which Tiwari was shown as Shekhar's biological father.
Tiwari had given blood sample for the DNA test on May 29, 2012 at his residence in Dehradun following the apex court's order in the case, after repeatedly contesting against undergoing the test on various grounds.
Tiwari's pleas had been objected to by Rohit who had filed the paternity suit in 2008, claiming the veteran Congress leader to be his biological father. Tiwari had refuted his claim.
