ANOTHER RIVER HAS “PERSONHOOD”

According to an item on Lowering the Bar, another river in India has been granted “personhood,” bringing the total to three: two in India and one in New Zealand.  According to the decision of the High Court of Uttarakhand that is quoted at Lowering the Bar, the two rivers in India have been “declared as juristic/legal persons/living entities having the status of a legal person with all corresponding rights, duties and liabilities of a living person.” 
As the Lowering the Bar author pointed out, and as should have been apparent from the questions I asked in my recent post on this subject, a river can’t actually exercise the rights and carry out the duties of a living person.  A living person has to do those things for the river.  So the river can’t actually have the status of a living person, at least not without someone else to actually make decisions for it.  Who gets to make those decisions, and who pays whatever costs result from them?
