Industrial relations – Industrial dispute. On application by the claimant Royal Mail Group, the Queen's Bench Division granted an injunction to restrain the defendant Communication Workers Union (CWU) from unlawfully calling strike action in locations across the United Kingdom. The court held that the striked call was unlawful. The dispute between the parties had not, in line with a collective agreement between themselves, been referred to external mediation. The CWU would still have the opportunity to call its members out on strike if external mediation turned out to be unsuccessful.
