Abstract
In this paper, it is proved that every oriented closed hyperbolic --manifold admits some finite cover with the following property. There exists some even lattice point on the boundary of the dual Thurston norm unit ball of , such that is not the real Euler class of any weakly symplectically fillable contact structure on . In particular, is not the real Euler class of any transversely oriented, taut foliation on . This supplies new counter-examples to Thurston's Euler class one conjecture.
