Norris was penalised in Montreal for slowing down too much behind the safety car from the hairpin to the pitlane, thereby purposefully opening a gap to team-mate Oscar Piastri so McLaren could perform a double pitstop without Norris risking losing a position to Charles Leclerc.
Norris was slapped with a five-second penalty which perplexed him at the time, and two weeks on the Briton says he is still none the wiser on why the stewards penalised him.
"We're still discussing it with the FIA, because they've set a new precedent with what you're allowed to do or not allowed to do," Norris said on Thursday.
"There's clear examples of people who did it, or did what they think I did, purposefully, and no penalties were given.
"Now they've basically said: 'You have to be on your delta the whole time.' So they're forcing you to go quickly under safety car, which doesn't make sense to me."
It has now emerged that the FIA has indeed gone back to a precedent, from the 2005 season, to curb the practice of drivers purposefully obstructing others ahead of a safety car pitstop, which is where Norris' penalty originated.
In the 2005 Chinese Grand Prix Renault driver Giancarlo Fisichella backed off to leave a gap to his team-mate Fernando Alonso, who was leading the race.
In doing so he held up McLaren's Kimi Raikkonen and Ferrari's Rubens Barrichello, allowing Renault plenty of time to get Alonso back out before serving the Italian, who received a drive-through penalty for the offence.
