Employer refuses to accept disability

Hi 

I need your views urgently. 

i have always found opinions and views here very useful as you guys are not only knowledgeable kind also.

At the moment, I am awating a pre-hearing for unfair dismissal and disability discrimination.I had a CMD and two other PHR couple of months ago. The Judge has ordered a lists of specific directions for both parties, but the Respondents law firm continuously breaching the ET Order, and despite my complaints it appears that they are unrelented in their inappropriate behaviour. 

The Judge Ordered me to provide all my GP documents including specialists reprot( diagnosed as having ASperger's) as regard my 'Disability' for Respondent to obtain their own medical report based on my disclosed documents.

Subsequently, Respondent referred me to be assessed by Respondents Occupational Health Consultant. On assessment, the latter agreed with my disability and recommended readjustments for return to work.

Unfortunately, on receiving their own Occupational Health report, they came back asking me to see a private consultant instructed by them in order to obtain a medical report as above purposefully, misinterpreting the Judge's Order. I refused to attend such an examination as I was not required to do so as per the Order. In turn, Respondent applied for an Unless Order, but Judge refused giving the same and agreed that there was no express reqirement in the Order, but Judge says as this is now clearly a dispute' whether a medical examination is necessary' he asked both parties to give submission in this matter in the forthcoming PHR.
i am surpised to that why has judge wanted to here a submission on the same matter when it was already discussed and agreed in the cmd that i have only to provide my medical documents to their specialist, besides seeing their occupational health for advice.  
Can a Respondent pursue the Judge by not complying the Order to reverse his own Order on the same issue??

I will be exremely  grateful for any advicce, opinion or views form all of you. And i promise I will keep you update.

NB. I am in notice period, ending in a month time.
