Movable ballast has been banned since lead shot was found in the water tanks of a Tyrrel (I think it was in 1984, correct me if I'm wrong : no time to research it) ... back then, they were allowed to top up the water tanks & many people think that the lead shot was added in order to push the car up to minimum weight.
So, yeah, Tyrrell said it was movable ballast & it has been banned ever since.
