Arizona Republic:  “Two taxi firms and a cabdrivers group want the Arizona Court of Appeals to block Phoenix from awarding a Sky Harbor taxi contract.   The contract, which takes effect Monday, gives three firms – Visum Transportation, Apache Taxi and AAA Cab Service – exclusive rights to pick up passengers at Phoenix Sky Harbor International Airport.  Visum and Apache were unqualified, said Shane Gosdis, a Phoenix lawyer who represents C-TO Transportation & Dispatching LLC, Ace Cab and the Independent Cab Driver Association at Sky Harbor Airport.”
