Yes, Judge Pass is easier than Corner Pass.
Judge Pass is closely associated with The Judge peak, so use that as a marker. If you find yourself slogging up a steep slope out of the valley and Popple Peak suddenly seems closer, then you've probably gone too far.

After descending the pass a little, it does traverse South a bit - don't miss that. If you find yourself endlessly clambering down a boulder-filled gully then you are probably off the trail.
Distance between the two passes is about 14km according to my own GPS tracks but that is obviously very route dependant.
Only security issues I'm aware of is the ongoing use of Judge Pass by the smugglers. Seems to be a significant route these days. Don't assume they are put off by the winter weather.
