All depends on the spec, doesn't it?
Either Rangers said fit us up with xyz or the contractors tendered to fit xyz. If xyz isn't there and the contractors have had the chance to provide it but have failed, the money's not due, at least not in full. But that's for the future. If there's a case on the face of it and the judge is nervous about Rangers' finance they may get the arrestment continued.
Btw, Boabie, desplte m'learned friend gs' advice, don't go rejecting that motor 'til you've crossed your lawyer's palm with silver or more likely, gold.
