Nor can deanimated cryos that some persons nitpick are "not really dead just frozen". You had me scratching my head there for a minute, George. But you are applying your quoted material to the entirely wrong context. The context is clearly stated as "to provide for the termination and
forfeiture of rights in certain unused burial spaces in such cemeteries". A space occupied by someone pronounced dead is not "unused". This entire "Act 46 of 1931" has to do with people who own burial plots and abandon or otherwise fail to maintain them according to whatever the particular cemetery's regulations are. Obviously, once the burial space is actually put into use, the occupant and former owner of it cannot come out from time to time to water the pansies or run a weedwhacker around the tombstone. Here is a link to the entire act:
Or if that stops working just Google up some of the text George quoted.
The legal protections for the deceased in cemeteries of which I speak are substantial and go back for centuries to the common law, along with much modern legislation. Just as it was a crime in the Middle Ages (and still is) to rob a grave in order to extract the gold fillings from somebody's teeth, it should be similarly a crime for anyone to mess around with the "cadavers interred" via CI's cryostats. I remain convinced that sort of protection is valuable and is nonexistent for whole body donors for research.
