Apparently that taxi company HATES customers. In any case, Justice. Yes, the sane thing to do would have been to take the pod to the Justice World (as they did) and stick it in the Justice Field for it to open. Which, I'm pretty sure, is what the crew intended to do. Then the bloody shoes came along and whisked them off, Rimmer got tried and sentenced and the crew forgot about the pod. They could have asked the Justice computer to take it off their hands after Rimmer was carted off and THEN deal with his trial, but instead completely forgot. Which, I guess, could happen. It is Red Dwarf, after all.
