Just an idle thought... not saying anyone ever intends to do so...
or how they could possibly be caught if they did..

but how does UK law stand on flushing a relative's ashes down the lav, or bin bagging them in the wheelie bin....????

I think, although, scattering over open fields and sea shores are regarded as legal fair game..
the bog and the bin do look more convenient in lousy British inclement weather.... 🤔
