I found a website that mentioned it in passing, with regards to the issue of consent. According to some law college somewhereorother:
The House of Lords held that consent was no defence and that each of the participants was guilty of ABH. This was only by a 3 to 2 majority but has been followed as it was a precedent set by the House of Lords.
Another website found had this to say about each of the men indvidually:

His accomplice, Peter Grindley, for the same offences and for possessing drugs, was also jailed for three and a half years.
