HRT may be in breach of contract for sidelining Narain Karthikeyan ahead of the British Grand Prix.
India Today claims the 34-year-old has made both of his scheduled sponsor payments to the Spanish team, guaranteeing his race seat at least until the end of July.
The report claims Hispania team figures are saying Karthikeyan is "still part of the team", despite the fact Daniel Ricciardo has replaced him at Silverstone off the back of a driver deal with Red Bull.
Karthikeyan as well as HRT, who are still running 'Tata' sponsor signage on the F111 car, have not responded to requests for comment.
India Today suggests the driver could be keeping quiet at the expectation of returning to the cockpit in Singapore, a month before India's inaugural Grand Prix.
The other HRT driver is Vitantonio Liuzzi, who on Saturday qualified half a second ahead of Australian rookie Ricciardo at Silverstone.
