We deal with a weak solution v to the Navier-Stokes initial value problem in R-3 x (0, T), that satisfies the strong energy inequality. We impose conditions on certain spectral projections of omega:= curly or just v, and we prove the regularity of solution v. The spectral projection is defined by means of the spectral resolution of identity associated with the self-adjoint operator curl.
