[Graham Boak]

But do all next of kin feel that way? Are there others who are happier to leave the dead to lie (once their whereabouts are known), and not be dug up just so some enthusiast can satisfy their hobby?

I'm not religious: in my opinion the dead are gone and their sensitivities with them, but surviving relatives who knew them when alive should be allowed a say - on both sides of the matter, if such exist. Once all such relatives are gone (and perhaps the ruling could be extended one generation?) then they are open to investigation as all preceding generations are, and without special pleading for occupations. But the investigation should be done with respect and for some real purpose in the extension of knowledge, not just to satisfy hobbyists or conspiracy loons.
