Robert Kraft just won a major battle in the war over whether that spa video ever sees the light of day -- a judge has granted a protective order that keeps it on lockdown ... for now.
In court docs, obtained by TMZ, the judge agreed with Kraft's attorneys that releasing the police surveillance video to the media would jeopardize the Patriots owner's right to a fair trial. As a result, the judge's order says the video cannot go public until the case is over -- whether that's by plea agreement or prosecutors dropping the charges -- or once a trial jury is sworn in for the case.
