West Norwood cemetery rang a bell (very belatedly I’m afraid). THe council were taken to court 20 odd years ago for vandalising many of the graves. It seems that at least part of the cemetery is subject to Faculty jurisdiction ie Church Courts - Southwark anglican diocese in this case.
This gives the background. — just read management summary first paragraph.
