Yes you can but what will it achieve. You have to ask yourself if you think that you can win a re-dress, if you do then go for that option. Did you receive a Mid Term Appraisal? If yes did they point out any shortcomings in that? If not then you should have good grounds, if you didn't even get a Mid Term then you definitely have grounds.
A Representation is all well and good but I'm not sure that boards rellay have enough time to read them fully, having already read your crappy CR/SJAR in the alloted time.
Bloody good luck with it though if it is justified and your report really is that unfair.
Not for nothing are the notes attached to CRs by disgruntled individuals known in Glasgow as "suicide notes".
You can't redress opinion-only fact or something that is so obviously outrageous. If it comes down to the fact that your OC doesn't like you or doesn't think you as good as you think you are then live with it. It has happened to me at various times over the years-most recently in my latest report. Life goes on.
