I’ve never been a supporter of the mosque, and it seems quite reasonable, to me, that the rents for a property be higher now than they were in 1972. If I were on the board of Con Ed, I’d be asking just who within the company managed the property, how it was they let it go so long without a rent adjustment.
But it still seems odd, to me, that a contract would allow rent increases to be imposed retroactively.
You go back to the time of the error. Not unusual.
