In contrast to the opinions raised last week by Liverpool manager Rafael Benitez, Ferguson has always maintained that the football authorities treat his club with vigour and railed against the original judgement, though did not appeal.
'Of all the things the FA has done to this club over the years,' said Ferguson at the time, 'that was one of the big shocks.'
And the issue was raised again when United were made aware that Nicholas Stewart QC, an ardent supporter of one of United's main rivals, chaired the four man independent disciplinary panel appointed by the FA.
There is no suggestion of impropriety on the part of Stewart, whose integrity is unquestioned, though Ferguson had reservations on the basis that there could be allegations of a possible conflict of interest.
And, according to a report in the Guardian newspaper, the United manager felt so strongly about it that his original programme notes for Sunday's 3-0 victory at Old Trafford explained his grievances, only to be toned down by chief executive David Gill.
The resulting comments were thus boiled down to a single paragraph which read: 'I am still shocked by the four-game ban handed out to Patrice following the incident at Stamford Bridge that saw him at odds with own of their groundsman.'
Though Gill is believed to share Ferguson's misgivings about the FA's treatment of United over Evra, his decision to intervene appears motivated by a desire to avoid confrontation with the governing body. Ferguson's views on his notes being edited are unknown.
Meanwhile, Evra himself took advantage of United's emphatic victory over Chelsea at the weekend to launch his own attack on the FA.
Evra played a full role in the victory, contributing to United's eighth consecutive clean sheet as well as setting up Wayne Rooney's second half goal, on his first game back after the suspension.
'I dedicate this victory over Chelsea to the English Football Association,' Evra said.
'I'm doing so because I am still unable to stomach having been given a four-match suspension by them.
'It is very pleasing to beat Chelsea by three goals, as they are one of our rivals for the title.
Evra did not complete the game after picking up a knock but revealed he will be in contention to start against Wigan on Wednesday, when United will attempt to reduce the gap between them and leaders Liverpool to two points.
'I hope it is just a minor injury,' he said. 'I will have tests on it, and we'll see what they have to say.'
