Human rights group FairSquare says Infantino – who became an IOC member in 2020 – has repeatedly breached the Olympic Charter and the IOC's code of ethics, most recently in his handling of the Folarin Balogun affair.
The United States striker's one-match ban was suspended by FIFA's disciplinary committee, freeing him up to play in their World Cup last-16 match against Belgium.
That followed a phone call from President Trump to Infantino, with the Swiss insisting FIFA's committees are entirely independent.
Britain's Times newspaper has reported that disciplinary committee chair Mohammad Al Kamali made the key decision to suspend the ban alone, having never been the sole arbiter in any published previous disciplinary cases.
FIFA has offered no explanation of why the ban was suspended.
FairSquare's complaint alleges five clear breaches of the IOC's rules on political neutrality, along with 'prima facie' evidence of two further serious breaches – including the handling of the Balogun case.
In December FairSquare made a similar complaint to FIFA's ethics committee. FairSquare said it had received acknowledgement that its complaint had been received, but has not had any further information.
The Norwegian football federation wrote to the FIFA ethics committee last month requesting it consider FairSquare's complaint.
Fifty members of the European Parliament wrote to the same committee on June 29 urging it to address FairSquare's complaint.
FIFA and the IOC have been contacted for comment.
