Apart from discussing the admissability of evidence it also has case law CDLA/1471/2004 from the Upper Tribunal, this also discusses the admissability of evidence produced after the original decision.
Basically, it is for the Tribunal to decide what is evidence and for the Tribunal to decide whether it should admit it.
Hope this helps

If a clerk to the tribunal has refused to accept evidence on those grounds then it sounds like they are in serious need of training and supervision.
I would consider contacting the tribunal service office you are dealing with and saying that you want to make a formal complaint to the regional tribunal judge about medical evidence being refused by a clerk.
Good luck,
Steve
