Responding to an RTI application, the Prime Minister's Office cited section 8(1)(h) of the transparency law, which exempts information that would impede the process of investigation or apprehension or prosecution of offenders. Nearly 2,000 people were killed in the post-Godhra riots.
The refusal could potentially raise questions whether the communications between Modi and Vajpayee contained any information related to rioters or people behind the riots.
The RTI applicant had also sought a copy of all communications exchanged between the PMO and the Gujarat government between February 27, 2002 and April 30, 2002 on the law and order situation in Gujarat in the aftermath of the riots.
But Modi has maintained that the then prime minister had said he was following "raj dharma".

Prime Minister Manmohan Singh at a poll rally in Jaipur on November 21 had attacked the Gujarat Chief Minister with a remark that a former prime minister had reportedly made on raj dharma. Without naming either leader, Singh said a BJP chief minister had faced so many allegations that a former prime minister had once told him to follow "raj dharma".
Seeking to rebut Singh's "raj dharma" jibe at Jaipur, Modi told an election rally in Gwalior that Vajpayee never pulled him up for not abiding by raj dharma, rather he praised him.
"Atal Bihari Vajpayee ne hamein rajdharma ka palan karna sikhaya aur hamne kiya. Isi se BJP sarkaron ki vahvahi ho rahi hai" (Vajpayee tutored me in rajdharma and I have adhered to it. This is the reason why BJP governments are being lauded everywhere), Modi had said.
