A senior Starfleet officer who sat as Space Command representative on the board that tried Captain Kirk at Starbase 11 in 2267 over the apparent death of Ben Finney.
Krasnovsky appears in the episode Court Martial as one of the four officers hearing the case against James Kirk at Starbase 11. He sits beside Commodore Stone, who presides, together with Captain Chandra and Lindstrom.
The board listens to the prosecution led by Areel Shaw, including the computer log that seems to show Kirk jettisoning the ion pod with Finney inside before a red alert had been called, and to the unorthodox defence mounted by Samuel T. Cogley.
When Cogley argues that his client has the right to face his accuser, the computer, the board agrees to reconvene aboard the Enterprise, where Finney is found alive and the charges collapse. Krasnovsky himself has almost nothing to say. He was played by Bart Conrad.
