The US Department of Justice (DOJ) is suing software giant Computer Associates (CA) over illegal price fixing.
The DOJ wants CA to pay around £880,000 ($1.3m) over claims that it restricted price discounts offered by takeover target Platinum Technology, before receiving regulatory approval for the eventual $3.5bn merger between the two firms.
CA said it would vigorously contest the "unfounded" charges.
At dispute is the role of an employee allegedly sent by CA to review Platinum Technology's operations. CA insists it did not exercise "beneficial ownership or operational control over Platinum" during the regulatory waiting period.
CA said it had taken reasonable action "needed to protect Platinum's business during the waiting period."
The lawsuit is further embarrassment for CA, which already this year has had to battle through a damaging proxy fight, defend press claims that it falsified accounts, and apologise for the quality of its customer service.
