Jailed actor Wesley Snipes' latest court appeal was denied by U.S. judges on Monday (06Jun11).
The Blade star began a three-year prison sentence in December (10) for neglecting to file income tax returns in 1999, 2000 and 2001.
But Snipes, who maintains his innocence and insists he was duped by tax advisors, recently filed an appeal to overturn the conviction.
However, that plea was shut down by the Supreme Court when officials refused the star's hearing.
The actor must now carry out the remainder of his jail term, according to CNN.
