Mike, this is one area I can agree with a lot of your points. The postion RB was photographed in is very peculiar.
RB was, IMO, moved and placed in that position after death. I see no reason for the murderer to do this. The murderer would simply leave RB sat in the chair he died in. If RB had fallen from the chair shortly after death, and before rig mort had set in, he would be slumped on the floor.
If however RB was knocked from that chair after rig mort had set in (and it clearly had) this, I believe had to done by someone other than the murderer and, as I have mentioned before, I am still surprised more of this wasn't raised at the trial.
If I had been a jury member and had seen this photo I would certainly have had a lot of questions about it!!
However if the police did stage RB body it does not make JB innocent, It simply adds to the incompetence of the police, which I suppose could have helped the defence undermine the prosecutions case 
Do you know how JB's current defence team is regarding this photo and have any queries relating to it been presented to the CCRC?

First of all, I do not think there can be much doubt if any at all, that Ralph's body was toppled from the chair behind the door through which the police entered the kitchen, and that at the time this occurred rigor mortis had already set in...
Secondly...
this photograph was not disclosed to Jeremy or his legal team, by the time of his trial at Chelmsford CC in October 1986, nor as I understand it by the time of his last failed appeal in 2002...
Thirdly, I should really explain for the benefit of everyone, how I came to end up in possession of this particular photograph, since I am sure everyone is puzzled as to why it was not utilizes during the trial or the appeal? Well, I came into possession of it, quite by accident whilst visiting Andrew Hunter at his Oxfordshire home. I had been fortunate enough to be invited to meet Andrew at his home to discuss features involved in the case, and during one such visit I saw the photograph in question amongst Andrews file on the case, and I asked if I could have a copy? At first Andrew was somewhat reluctant to give me a copy, but after I agreed to him blanking out the ghastly image of Ralphs body, he provided me with the copy that is posted on the forum. I have never asked Andrew where he got a copy of that photograph from, but I can say that it was not part of the court album (50) and as far as I know it was not part of the master copy album (223)?
I am sure a great many of you are already aware that Andrew Hunter raised questions in Parliament about Jeremy's case, and I assume he took possession or was given possession of such a photograph, and possibly others, as part of his investigation into these/those matters?
