  There has been an increasing interest on the concept of Inelastic Dark Matter
(iDM) - motivated in part by some recent data. We describe the constraints on
iDM from the results of the two phase dark matter detector ZEPLIN-II, which has
demonstrated strong background discrimination capabilities (>98%). Using
previously published estimates of the ZEPLIN-II residual background, the iDM
limits presented here exclude a significantly larger iDM parameter space than
the limits derived without background subtraction. Moreover, assuming standard
xenon quenching factor (qXe) of 0.19, our ZEPLIN-II limits strongly suggest the
exclusion of iDM signal claims at >99% C.L., for Weakly Interacting Massive
Particles (WIMPs) masses >100 GeV.
