California imposed sanctions on individuals employed by its men's basketball program for NCAA rules violations the athletic department discovered in 2008.
The violations related to the frequency and number of phone calls made by coaches to recruits.
The department said in a statement that it "quickly" self-reported the findings to the NCAA and the Pac-10.
"Internal and external investigations have already concluded that the violations were not intentional," the school said in its statement. "Because the NCAA Committee on Infractions is currently considering the final disposition of this case, we will have no further comment until a final decision is rendered."
FoxSports.com reported that Cal coach Mike Montgomery and members of his coaching staff appeared Friday in front of the NCAA's Committee on Infractions in Indianapolis.
Montgomery, the former chairman of the National Association of Basketball Coaches' ethics committee, was named Cal's coach in April 2008. The former Stanford and Golden State Warriors coach has led Cal to two NCAA tournament appearances, and last season Cal won its first regular-season conference championship in 50 years.
