  Massive Gravity in four dimensions has been shown to be free of the
Boulware-Deser (BD) ghost in the ADM language for a specific choice of mass
terms. We show here how this is consistent with the St\"uckelberg language
beyond the decoupling limit, and how the constraint required to remove the BD
ghost arises in this framework nonperturbatively, without the use of field
redefinitions. We emphasize a subtlety in obtaining this constraint, that has
been overlooked in previous literature. In both the ADM and St\"uckelberg
formalisms the vanishing of the determinant of a Hessian guarantees the absence
of the BD ghost.
