Yes, but be careful when and how you do it.

Judges taking bribes is a big deal, and a Judge getting caught doing it is catching a brutal sentence; 20 years minimum on an off-world penal colony with an atmosphere so harsh they need to surgically alter people to breath. Corrupt Judges tend to rapidly become desperate and dangerous if they fear getting caught, and with the power they have they can ruin your life in a heartbeat. A crooked Judge is capable of virtually anything, and is a threat to your well-being not to be taken lightly.

Your best shot is going to be to drop an anonymous tip somewhere outside the Judge's immediate jurisdiction. Contact the next precinct over, and inform them of the name of the Judge, and the exact location and time of the bribe. From there, two units get involved; the Public Surveillance Unit (PSU) and the Special Judicial Squad (SJS).

The PSU controls every piece of monitoring equipment in the city, and if the Judge did their deal in a public (or even many private) spaces, they have a hi-def video of it. Of course, an entire Mega-City wired for picture and sound means an insanely high noise/signal ratio, hence why it's critical for them to know there's something to look for, and for you to be as precise as possible to give them the best chance of finding the right needle in their legendary pile of needles. 

The SJS is the Internal Affairs department, "the Judges who judge the Judges". Their power to fuck up a Judge's life equals or exceeds the power a Judge has over a random citizen; they can (and will) force entry on a Judge's living quarters unannounced, pump them full of truth serum, and interrogate the hell out of them, not because of any accusations but *just at random*. Of course, this much power in the hands of a small group, ironically, is itself ripe for cultivating corruption, and the SJS has become crooked in the past. Ironically, this works in your favor, since the SJS needs to keep booking, cooking, and incarcerating actually corrupt Judges both to preserve their sweet position in the organization and to point the finger at someone other than themselves. Your bribe taker could easily find himself a scapegoat for the real crooks among the Judges.
