RALEIGH, N.C. -- North Carolina is challenging the NCAAs jurisdiction to pursue charges in the schools long-running academic fraud scandal and is holding off on self-imposed penalties.The school on Tuesday publicly released its response to five potentially top-level NCAA charges, which include lack of institutional control. UNC acknowledged problems tied to irregular courses in a department popular with athletes but also available to non-athletes on the Chapel Hill campus, though it argued that its accreditation agency -- not the NCAA -- was the proper authority to handle such a matter.That agency, the Southern Association of Colleges and Schools Commission on Colleges, sanctioned the school with a year of probation that expired in June.UNC made several procedural arguments before responding to each charge outlined in a Notice of Allegations (NOA) sent in April. Its response is a procedural step that will eventually lead to a hearing followed by a ruling in a case likely to push into 2017.The NCAA enforcement staff now has 60 days to respond.We had classes that didnt meet our rigor, UNC athletic director Bubba Cunningham said in a teleconference with reporters, but whether or not thats a violation of a bylaw is what were asking the Committee on Infractions to determine.None of the charges was tied solely to the existence of the problematic classes in the formerly named African and Afro-American Studies (AFAM) department. UNCs response cites an internal NCAA report from March 2013 that stated as much, but adds that the document wasnt provided to school officials.Rather, the response states, UNC representatives discovered it by happenstance after traveling to NCAA headquarters to review case files in person in July 2015.The multiyear case grew as an offshoot of a 2010 probe into the football program. UNCs response referenced that earlier case, noting the NCAA investigated whether academic counselors had provided improper assistance to athletes before issuing sanctions in March 2012.UNC argued that a ruling is final, binding and conclusive according to NCAA bylaws, so the March 2012 sanctions should have precluded later charges that could have been resolved previously. That points to a current charge against former faculty chairwoman and womens basketball academic adviser Jan Boxill for providing improper assistance and suggesting a grade in a course on at least one occasion between February 2003 and July 2010.The school also cited an expired four-year statute of limitations.UNC raises these jurisdictional and procedural issues not to excuse the underlying conduct or to escape accountability for those events before its accreditor or elsewhere, the response states, but rather to ensure mutual adherence to the rules that govern NCAA enforcement actions, including this one.As a result, the jurisdictional and procedural issues make it difficult ... to assign appropriate penalties for the alleged violations, the response states.Individually, UNC disputed the institutional-control charge. It accepted that Boxill provided improper assistance in 15 of 18 cited instances, though it disagreed that she engaged in unethical conduct and suggested the charge be treated as a less-severe Level III case instead of a Level I.It also accepted that it failed to properly monitor Boxill as part of a broader oversight charge that spanned from fall 2005 to summer 2011, but suggested it be a Level II violation.Randall Roden, a Raleigh-based attorney representing Boxill, provided The Associated Press with a copy of Boxills separate response. It denies wrongdoing in the opening sentence.It did not happen, it states. Not one of the allegations against Jan Boxill is true.The case centers on independent study-style AFAM courses requiring a research paper or two while offering GPA-boosting grades. Many were misidentified as lecture courses that didnt meet.A 2014 review by former U.S. Justice Department official Kenneth Wainstein estimated more than 3,100 students were affected between 1993 and 2011, with athletes across numerous sports making up roughly half the enrollments.The NCAA reopened its case in 2014 and first filed charges in May 2015. UNC was near its response deadline when it reported additional information for review, pausing the process for eight months until the arrival of a new NOA.---Follow Aaron Beard on Twitter at http://www.twitter.com/aaronbeardap Cheap MLB Jerseys Authentic .

Red Bull boss Christian Horner says Mercedes must consider if its current driver line-up is tenable in the long term after another collision between Lewis Hamilton and Nico Rosberg in Austria.Hamilton won in Spielberg despite a last-lap clash with teammate Rosberg, who had been leading the race but had to settle for fourth due to damage from the incident. The collision nearly elevated Max Verstappen to a victory in a scenario which would have been similar to his maiden win in Barcelona earlier this year, which came after the Mercedes drivers crashed out while vying for the lead on the opening lap.When it was put to him that he must want the collisions to continue as a rival team boss, Horner said: You always want to win on merit and it is never good to benefit on others misfortune. But youve got to be there to capitalise.I think for Mercedes, in the long term, how tenable is it for that pairing to continue as a team?Rosbergs contract expires at the end of the current season, though Mercedes have said the Austria clash will have no impact on extension talks.Horner was then asked if one solution was to have one driver of a different calibre to the other, and he replied: While theey are in the situation they are in with the competitiveness they have and the closeness of performance they are obviously going to have these issues and will not be isolated to this race.ddddddddddddThat is an attractive element for the sport and I think when you have got a dominant car it is great to see the cars going head-to-head.Horner has experience of managing a tricky teammate rivalry, with Sebastian Vettel and Mark Webber enduring a difficult relationship in their five years at Red Bull together. With Mercedes now considering team orders Horner says that in itself is a tricky situation for any team to properly implement.It is enormously difficult because no matter how much those guys says they are team players they are contractors and racing for themselves. They are going for the biggest prize in motorsport.Inevitably they will do what is right for them. I think theyve got sufficient margin over the rest of the field why do they need to consider that. It creates interest in F1 which it needs with two teammates who may not be best of mates. ' ' '
