Although it originally indicated that it would accept IndyCar's appeal panel ruling on the matter, General Motors has taken up the option of appealing the original decision by IndyCar to allow Honda to make a change to its single turbocharger. GM's initial protest regarding Honda's use of a 0.74 A/R compressor cover was denied April 26.

The new appeal hearing will be held May 9 in Indianapolis, two days after the series' open test at Texas Motor Speedway and a day before rookie orientation begins at Indianapolis Motor Speedway for the month of May.

This appeal decision will be final and binding, per Rule 13.11 of the IZOD IndyCar Series rulebook. IndyCar's president of operations and strategy Brian Barnhart has elected to utilize a single individual, retired Indiana Supreme Court Justice Theodore R. Boehm, to hear the proceedings.

Boehm's time in court ended in September 2010, and has experience as a private lawyer, in-house counsel and managing partner of an Indiana law firm.
