Thanks for your reply.
You're right in that had a mistake not been made, the first attempt at the SDs may well have been successful, but we're all human and all make mistakes. If fair allowance is not given for a simple, honest mistake on an unfamiliar form, that seems deeply unfortunate. However, two identical PE2s had a different outcome, and (as mdann52 pointed out) the difference is that TfL failed to contest one of them. It also strikes me as unfair that TfL submitted two sides of A4 in response to our tiny boxes of writing on the PE2 and PE3 - had we known we could attach a separate sheet, we would have done so (and no doubt constructed a more compelling argument in the process!), but when there's no indication that you're allowed to do that, and you've just had two forms rejected for minor admin issues, I think we can be forgiven for thinking we had to stick to the rules!
The SD for the second OfR was submitted together with the first (and stamped as received by the TEC well within 21 days, despite a 9-day postal delay). Of course both initial SDs contained the same error (role of "verifier" not specified - both my other half and the solicitor missed that this was necessary). The second attempt was corrected, but she then ran into the issue she needed a PE2 for each PCN, but only submitted one to cover both.
However, I would argue that both errors could at least in part (to the point where the benefit of the doubt could be given) be explained by the process:
1) That the forms originally supplied (with a green-printed background) did not highlight in (unprinted) white, unlike everywhere else on the form, that the respondent had to complete the section regarding the role of the "verifier". Ironically, the plain black/white copy one can download is clearer in this regard.
2) That (for the second attempt) the TEC supplied two PE3s and one PE2, implying that one PE2 would do the job for both, when it would not.
...of course this argument might not get me far, and point 1 seems particularly difficult to argue in the cold light of day, but if two intelligent graduate professionals (my other half and the solicitor) could get it wrong, one might argue that the process is unclear and not fit for purpose!
Would a full breakdown of the timeline in list form be useful? I appreciate that it's all dotted around this thread in response to specific questions.
cheers
