The central boss on the clutch plate sticks out further on one side than the other so if it is fitted the wrong way round it will bind on the cover plate and the clutch wont operate. I had a similar problem on one of my Commers (same clutch) and it turned out to be a poorly manufactured plate where the central boss wasn't positioned properly.
I know we have discussed this before (a few years ago) but....are you sure that the slave cyliner is installed correctly i.e. at the gearbox side and not at the engine side? The second mistake which is possible is that the bleeding nipple is placed in the wrong hole, it should be in the upper hole of the slave cylinder. If there is not made a mistake regarding the above, there is not much else to do than checking the position of the clutch plate. I have never heard of this before but there is always a first time I am afraid. I don't know what you have done with the clutch, but if you have installed new parts then the possibility is there that the after markt parts are not being produced very well. I know of examples of clutch cover assemblys which were of the wrong hight with the result that the clutch could not come free. Just some thoughts....
