[JURIST] US-based Eller & Co. [corporate website] said Friday that Britain's Court of Appeal [official backgrounder] has agreed to hear on Monday its petition for appeal against a High Court ruling approving the takeover of British shipping company P&O [corporate website] by United Arab Emirates-owned Dubai Ports World (DPW) [corporate website], which would grant DPW control of six major US ports. The Court of Appeal will immediately hear Eller's case if its petition for appeal is granted. Judge Nicholas Warren approved Dubai Ports World's acquisition of P&O [JURIST report] Thursday, but his ruling will not become effective unless the Court of Appeal refuses to hear Eller's appeal. Warren placed a hold on his ruling to permit Eller to appeal to the higher court directly. AP has more.
