The Delhi High Court on Thursday reserved its order on a paternity suit filed against veteran politician and former Andhra Pradesh Governor N D Tiwari by a youth claiming to be his son. A Bench comprising Justices Vikramajit Sen and Manmohan Singh reserved the order after the octogenarian politician vehemently opposed against entertaining such a petition which has been filed 31 years after the youth was born. The Court was hearing a petition filed by Rohit Shekhar,seeking its direction to declare Tiwari as his biological father. Shekhar filed an appeal before a Division Bench challenging a single-bench order which had dismissed his petition on the ground that it was not maintainable. Justice S N Dhingra had on November 3 last said the suit filed by Shekhar was not maintainable and allowed the plea of 84-year-old Tiwari who had sought dismissal of the petition. The Court had said it has no territorial jurisdiction to hear the case as Tiwari,then Andhra Pradesh Governor,was in Hyderabad and a suit against him could be filed only in that city.
