The phrase "assumption is inconsistent" is correct and usable in written English.
It can be used when discussing a situation where a particular assumption does not align with the facts or logic of a given scenario.
Example: "In this analysis, we found that the assumption is inconsistent with the data we collected, leading to flawed conclusions."
Alternatives: "assumption is contradictory" or "assumption is incompatible".
Goldblatt v. Hempstead, 369 U.S. 590 (1962), does appear to assume that the inquiries are the same, but that assumption is inconsistent with the formulations of our later cases.
This assumption is inconsistent with 802.11 basic access scheme.
However, this assumption is inconsistent with the reality when considering the characteristics of different service applications.
This assumption is inconsistent with the geodetic observations that show rapid compressional deformation of the Japanese Islands; rheological studies suggest that considerably high stress is required to deform the island-arc crust (Shimamoto1993; Muto and Ohzono2012).
However, this assumption is inconsistent with the law of mass action.
Some of these assumptions are inconsistent with more recent evidence.
We know however, that these regulatory assumptions are inconsistent with the known biological effects of low doses.
The assumption is often inconsistent with the reality related to environmental protection.
Furthermore, the assumption of adiabatic mass loss is inconsistent with binaries in which the orbital timescale is longer than the mass-loss timescale.
The problem caused by the assumption of fixed bit location, which is inconsistent with the actual drilling, is solved by simulation of dynamic well bottom using virtual grid.
With (tau) interpreted as the local rise time, setting (tau = infty) is inconsistent with the assumption that the seafloor completes its deformation over a timescale smaller than the tsunami propagation time over horizontal wavelengths characterizing the deformation profile.
