I wish they would go away also. Not fulfilling his contract? wasn't it them who basically gave his drive away to another driver anyway. Really hope they go bust!
Reading between the lines, it would appear that:
Chandhok promised to bring in £xxx of sponsorship money to the team.
This money never materialised (or not all of it).
HRT responded by suspending Chandhok (until he came up with the funds).
This money still didn't arrive and so Chandhok never drove for HRT again.
HRT didn't want to attract negative publicity so simply told the media that Chanhok's "benching" was merely as a result of the driver rotation policy.
Obviously, money is tight at HRT, so they are looking to gain some form of compensation.
HRT would argue that they are a new team who NEED a driver who brings money to the team. If the driver fails to bring this money in, in effect, he has reneged on the agreement. HRT would further argue that had Chandhok been honest and told them that there was no money, they could've hired another driver who would've brought money in to the team. That money would've been used to develop the car, which would've brought in more points, attracted better sponsors, which in turn, would've helped HRT stay afloat.
There are 2 sides to every story and don't assume that Chandhok is not at fault. F1 is all about money and if it means that the team goes bust (possibly as a result of Chandhok), HRT would have every right to be aggrieved.
Chandhok would've been thinking that if he can show other teams that he is a good driver, even if he gets fired by HRT, he will have done enough to earn a drive with another team for 2011. This was always going to be a risk but it's easy to see why he took this risk.
Of course, this has A LOT of assumptions. It will be interesting to see what happens, if and when this goes to court. HRT could well win some form of settlement.
