Consultants will advise Birmingham City Council on how to deal with two conflicting bids for a super-casino.
Independent experts are to examine rival attempts by Birmingham City Football Club and the National Exhibition Centre to establish one of the country's first regional casinos.
Both schemes involve building on land which is owned by the council.
The decision to bring in expert advice, approved by the cabinet on Monday, is designed to show that the council is approaching the matter with an open mind since it stands to reap financial benefits by selling land.
A claim that council officers were instructed to help to prepare the NEC casino case but had not given the same level of advice to BCFC was levelled by cabinet regeneration member Ken Hardeman last month.
A report to the cabinet by David Pywell, the council's strategic director of development, underlined the need for both proposals to be treated fairly.
Mr Pywell warned: "The council has been approached by both the NEC and BCFC with a view to the city disposing of land.
"It is important to stress that the city's actions proposed under this report are only in its capacity as landowner.
"The city must not prejudice, thwart or pre-judge any of its statutory functions whether either in its capacity as planning authority for the Birmingham area or as a regulatory authority for the same area.
"Opinions among members of the council are strongly divided on the merits and potential locations of casinos and it is therefore suggested that the appointment of an independent adviser to assist the council in its decision as landowner would be beneficial."
Mr Pywell said the NEC's proposal for a casino was consistent with its business plan.
A leisure and entertainment complex named MGM Grand at the NEC would include a casino, bars, restaurants and a hotel next to the Pendigo lake.
The scheme would transform the west end area of the lake, creating an iconic vista and act as a catalyst for future expansion and development, he added. The BCFC casino would be part of a major development including a new 50,000-seat stadium on a 50-acre site at Saltley. The stadium would be the first of its kind in the UK to be used for soccer, rugby and cricket.
The regenerative effects of the ambitious scheme would trigger the development of the rest of the site into a " mixeduse leisure and sports destination" Mr Pywell said.
Council leader Mike Whitby said: "We have to make sure there is fairness in the way we approach this."
A casino advisory panel appointed by the Gambling Commission begins work this month on advising the Government about the interest displayed in gaming centres by local authorities. Ministers remain committed at the moment to only one supercasino, although there is speculation that four or five licences may eventually be approved.
The final recommendation on a preferred site in the West Midlands is likely to rest with the regional assembly.
