Dassault has made it clear that it was "technically and practically not feasible to stick to the present obligations" as it is wary of encountering the fate of British telecom company Vodafone, which is facing problems over taxation issues.
In the contract, Dassault wants to be held responsible for only the first 18 aircraft to be supplied by it along with the kits to be supplied by it for the remaining 108 aircraft to be produced by the HAL in India but the Defence Ministry wants it to take responsibility for the quality and timely delivery of all the 126 aircraft.
The French firm also does not want to be held responsible for the delays in the delivery of the aircraft to be manufactured by the HAL and has told the Ministry that it cannot be held responsible for paying the liquidity damages in case there are delays by HAL, they said.
Dassault fears it may land up in a Vodafone-like situation in terms of taxation for transfer pricing if it agrees with present obligations and such a thing can impact it adversely in a big way, sources said.
