The Hoosier Lottery’s largest vendor is protesting Indiana’s decision to award a private management contract to a rival company.

The Indianapolis Star reports that Scientific Games argues in an October 5th letter that lottery officials discriminated against the New York-based lottery vendor throughout the contract selection process.

The State Lottery Commission chose Rhode Island-based GTECH last week to run the lottery’s marketing, sales and distribution services. Officials announced Friday that the state had finalized a 15-year contract with GTECH.

Scientific Games’ letter includes the argument that lottery officials failed to take into account transition costs that would be lower for Scientific Games since it is the Hoosier Lottery’s largest current vendor.

Lottery officials responded in a letter by denying the allegations and asking Scientific Games to be more specific.
