The NCAA says North Carolinas argument that the governing body lacks jurisdiction in the schools ongoing multi-year academic case is without merit.In a Sept. 19 filing released by the school Tuesday, the NCAA enforcement staff pushed back against the schools procedural arguments in response to five serious charges by saying all the arguments lacked merit. UNC had argued that its accreditation agency -- which put the school on a year of probation that expired over the summer -- was the proper authority to handle such a matter instead of college sports governing body.UNC also argued that there was an expired four-year statute of limitations and a March 2012 ruling in an earlier case should have precluded some of the current charges.In addition, the school said that some material from an outside investigators report into academic irregularities on the Chapel Hill campus shouldnt be used because interviews werent performed to NCAA protocols.Indeed, its response rests almost entirely on these procedural issues and touches only minimally on the underlying substantive facts, the enforcement staffs reply states.After noting that many of the procedural issues had been addressed with the school previously, the documents states: The parties explored each at length throughout this case and each is without merit.North Carolina is scheduled to appear before an infractions committee panel in Indianapolis on Friday in what amounts to a pretrial hearing. The focus will be the procedural arguments and not the facts of whether violations occurred, including lack of institutional control.The case grew as an offshoot of a 2010 inquiry into the football program.

That included a letter from an attorney representing the school pointing out that the NCAA was aware of the key AFAM issues in 2011 during the earlier joint investigation, yet it didnt charge the school with additional violations before issuing its March 2012 sanctions against the football program.This was not a different case than what was investigated in 2010-11, decided in 2012, and revisited in 2013, the Oct. 19 letter from Richard J. Evrard states.None of the NCAA charges is tied solely to the existence of the problem AFAM courses. Rather, they are focused on failures in oversight.The timeline is likely to carry this case well into 2017, approaching seven years since NCAA investigators first arrived on campus in the original football case focused on improper benefits and academic misconduct.
