In a unanimous decision on Friday, the Ohio Supreme Court ruled against MTR Gaming Group in its suit questioning the validity of petition signatures to get a constitutional amendment authorizing the building of four casinos in Ohio on the November ballot. The Court stated that MTR failed to prove that the disputed signatures were included in the total number of signatures certified by Secretary of State Jennifer Brunner as valid, and that they did not submit as evidence most of the disputed portions of the petitions being challenged. Due to the lack of evidence presented, the Court found that Brunner was not required to invalidate any additional signatures or conduct any further investigation. The casino measure will appear on the November ballot. MTR is expected to fund political advertising opposing the measure.
