  The impossibility of describing measurement in quantum mechanics while using
a quantum mechanical model for the measurement machine, remains one of its
central problems. Objective collapse theories attempt to resolve this problem
by proposing alterations to Schroedinger's equation. Here, we present a minimal
model for an objective collapse theory that, in contrast to previous proposals,
does not employ state dependent stochastic terms in its construction. It is an
explicit proof of principle that it is possible for Born's rule to emerge from
a stochastic evolution in which no properties of the stochastic process depend
on the state being evolved. We propose the presented model as a basis from
which more realistic objective collapse theories can be constructed.
