Per Curiam.  In the district court, the defendant
challenged the government's refusal to move for a downward
departure under U.S.S.G.  5K1.1.  The defendant made no colorable
claim that the refusal to depart was based on an unconstitutional
motive; instead, he asserted only that he had supplied sufficient
assistance to the government to require a departure motion.  This
does not avail in the face of a plea agreement that explicitly
preserved to the government "the sole discretion" to decide whether
to file a motion for departure based on substantial assistance. 
See Loc. R. 27.1.
Affirmed.
