TOPEKA, Kan. (AP) — A multimillion dollar income tax dispute involving a former Kansas businessman could influence whether Gov. Sam Brownback signs a bill allowing taxpayers to challenge rulings of the state’s Board of Tax Appeals.

Brownback spokeswoman Eileen Hawley told The Wichita Eagle the governor hasn’t decided whether to sign a bill that passed on the final night of the legislative session this month.

The measure would allow any taxpayer appealing a decision by the tax board to have a new trial in district court, where new evidence could be presented.

The governor’s office tried to restrict such trials to property tax appeals.

Pizza magnate Gene Bicknell is suing to force the state to refund $42 million he paid in 2013 after an unfavorable ruling by the then-Court of Tax Appeals.
