Tribunals – Requesting a Statement of Reasons & recording

At recent pip appeal, i was awarded standard mobility (upgraded from zero). i was not awarded daily living and do not want to contest the decision.

This being so, i read on B&W that "Whether you are considering appealing to the Upper Tribunal or not, there can be good reasons for requesting a Statement of Reasons (SoR), from the judge of your (first tier) Tribunal."

Presumably this is in relation to the review in a few years, or are there other reasons?

Two potential disadvantages to requesting a statement of reasons are cited:

1. You should be aware when requesting a SOR, having won your Tribunal, that a copy will also be sent to the DWP. Whilst unlikely, this does mean that they may consider an appeal of the Decision, where previously they may not have.

2. You should also be aware that if the Tribunals Service are unable to locate the Record of Proceedings for your case, they will be unable to produce a SOR and are likely to refer the case to a Judge to ask for the decision to be set aside. Whilst this might be good news if you lost your appeal, as the case would then be reheard by a different panel, you may be less happy with this outcome if you did receive an award at your hearing since that decision would no longer stand.

I don't think I'm at risk from no.1 because at the close of the tribunal the DWP attendee themselves suggested the upgrade of the mobility award.

So as regards risk no.2, is this a realistic risk that the court might lose the record and so have to re-try (which i wouldn't want to go through again)? How often has it happened?

Thank you BIS.

What are the reasons to request it if not appealing?
