— The University of North Carolina at Chapel Hill released a 73-page response Tuesday to the NCAA's amended Notice of Allegations related to academic irregularities involving student-athletes. In the response, UNC admitted wrongdoing but challenged the NCAA's authority on a number of allegations.

UNC disagreed with a charge of "lack of institutional control" stating, "Issues related to UNC–Chapel Hill’s academic irregularities are the proper subject of review by SACSCOC, its accrediting agency – not the NCAA, its athletic association."

"We work with an accrediting agency; the NCAA is the athletic agency," UNC athletics director Bubba Cunningham said Tuesday in a conference call. "We think they have different jurisdictions."

UNC is also challenging all academic related charges, including "failure to monitor," on both the NCAA's statute of limitations (four years) and the NCAA's "jurisdiction over the academic affairs."

"UNC-Chapel Hill accepts full responsibility for its serious past academic problems, and it has addressed them directly without regard to cost or reputational harm," the response reads. "But ... The question is whether the matters raised by the ANOA meet the jurisdictional, procedural, and substantive requirements of the NCAA constitution and bylaws."

Mentioned more than 100 times in the amended Notice of Allegations, was Jan Boxill, former faculty chairwoman, ethics professor and the former athletic-academic counselor for the women's basketball team. Boxill is accused by the NCAA of committing 18 different violations. The sum of Boxill's violations amounts to one of the five Level I infractions the NCAA alleges against the university.

UNC has countered, saying Boxill only committed 15 violations and they should amount to a Level II infraction because "she did not knowingly provide extra benefits as alleged by the enforcement staff."

The university did, however, acknowledge their failure to monitor Boxill.

"The University failed to adequately monitor Boxill, an ASPSA academic counselor whose service as a faculty member and in other roles on campus raised important compliance issues," UNC said.

In a statement released by her attorney, Boxill denied all allegations against her, arguing that she was unaware any of her assistance could be considered impermissible.

"Jan Boxill’s interactions with students were conscientious efforts on her part to teach students by meeting and talking to them for hours and hours, monitoring their progress, explaining and critiquing their work, correcting their mistakes and helping them learn how to do college level academic work," the statement reads.

"We feel like we have been very cooperative, open and transparent," said Cunningham. "The university is going to let her response speak for itself."

Julius Nyang’oro, the retired head of the then-Department of African and Afro-American Studies, and his assistant, Deborah Crowder, each drew one allegation for their failure to cooperate with the NCAA on their investigation. The university said they accept the charges against them because they "could not compel Nyang’oro and Crowder, former employees, to cooperate."

A public copy of the response was made available on the Carolina Commitment website one day after the university formally submitted the response to the NCAA. UNC requested, and was granted, a one-week extension by the NCAA to deliver the response. Their 90-day time to respond expired July 25.

UNC will now await the NCAA's response to the admissions, which typically is delivered within a month. They will then arrange a date to meet with the NCAA Committee on Infractions. It is at that meeting where they will learn whether the university will be subject to any punishment. The NCAA generally takes between eight and 12 weeks to deliver that after the hearing which could push the finality of the investigation into 2017.

"It's a very important step in Carolina's history to proceed," said Cunningham.

In its second investigation into academics and athletics at UNC in five years, the NCAA found the university to have committed five Level I violations – the most severe. Included among them were “lack of institutional control” and "failure to monitor" for the years in which counselors allegedly guided student-athletes into courses in the Department of African and Afro-American Studies (AFAM) that never met, that had few academic requirements and in which grades were manipulated.

After the NCAA delivered that Notice of Allegations in June 2015, UNC found and self-reported two new NCAA violations involving women's basketball and men's soccer in August 2015 that delayed the response.

"It does appear that women's basketball could be at risk," Cunningham said. "But none of the women's basketball coaches were named. Coach (Sylvia) Hatchell has our complete support."

Men’s basketball, football and women’s soccer – all of which were mentioned in the initial set of allegations – were absent from the amended NOA that was released in April.

No current coaches at UNC were named in the latest allegations.
