We study the problem of partial supersymmetry breaking in extended supergravity, using techniques developed in the context of the positive-mass theorem of general relativity. We show a number of identities that simplify the search of partial breaking. As an example we show that a general N = 2 supergravity, formulated in 4 dimensions, cannot break to N = 1 supergravity if the cosmological constant vanishes.
