Canada's Alcan has confirmed that it has begun an action in the German courts to have its pie emptive rights confirmed and declared enforceable" with regards to the 50 percent stake in the Aluminium-Norf the Aluminium-Norf rolling mill, which will pass to Norsk Hydro when the Noorwegian company completes its acquisition of VAW. Alcan, which owns the other 50 percent of Europe's largest aluminium rolling mill, said that three had been a reluctance on behalf of VAW and its previous owners E. on "to recognise Alcan's rights". Alcan clamis to have an agreement that gives it a right to match any bid for the mill. The situation is complicated because Norsk Hydro bid not only for Norf but for all of VAW Aluminium's operations.
