NFL owners unanimously approved changes to the league personal conduct policy Wednesday, but Commissioner Roger Goodell will retain authority to rule on appeals. Juan Agudelo Jersey .A special counsel for investigations and conduct will oversee initial discipline, Goodell said.This will be a highly qualified individual with a criminal justice background hired as soon as possible for the newly created position, Goodell said. The person will oversee our investigations and decide the discipline for violations of the policy.The commissioner also may appoint a panel of independent experts to participate in appeals.After the Ray Rice and Adrian Peterson cases, a more extensive list of prohibited conduct will be included in the policy, as well as specific criteria for paid leave for anyone charged with a violent crime.A suspension of six games without pay for violations involving assault, sexual assault, battery, domestic violence, child abuse and other forms of family violence will be in effect, but with consideration given to mitigating or aggravating circumstances.The policy is comprehensive. It is strong. It is tough. And it better for everyone associated with the NFL, Goodell said.The players union has sought negotiations with the NFL on any revamping of the policy, and said Tuesday it would reserve the right to take any and all actions should the owners act unilaterally. The union could consider Wednesdays vote by the owners as a violation of the collective bargaining agreement reached in 2011.Among the unions options is pursuing a grievance with the National Labor Relations Board. The players could argue this policy is a change in terms and conditions of employment; the NLRB Act says such changes in unionized situations are subject to collective bargaining.The union also could consider filing an unfair labour practice charge with the NLRB.We expected todays vote by the NFL owners from before Thanksgiving, NFL Players Association spokesman George Atallah said on Twitter. Our union has not seen their new policy.That new policy will include a conduct committee made up of several team owners that will review the policy at least annually and recommend appropriate changes. That committee will seek advice from outside experts, the NFL said.Members of the committee will be Arizona Cardinals owner Michael Bidwill as the chairman; Atlanta Falcons owner Arthur Blank; Kansas City Chiefs owner Clark Hunt; Dee Haslam, the wife of Cleveland Browns owner Jimmy Haslam; Dallas Cowboys executive vice-president Charlotte Jones Anderson, chairwoman of the NFL Foundation; Chicago Bears owner George McCaskey; Houston Texans owner Robert McNair; and two former NFL players who have a stake in NFL team ownership, Warrick Dunn of the Falcons and John Stallworth of the Steelers.NFL general counsel Jeff Pash said Wednesday in a conference call that it was a mistake in the past to rely solely on the criminal justice system for looking into legal issues. And he said the commissioners role in handing out discipline is not subject to collective bargaining.Last month, an arbitrator threw out Rices indefinite suspension by the NFL for hitting his then-fiancee in a hotel elevator, freeing him to play again.Former U.S. District Judge Barbara S. Jones said Goodells decision in September to change Rices original suspension from two games to indefinite was arbitrary and an abuse of discretion.After noting the two-game suspension given to Rice was insufficient, Goodell had changed the minimum punishment under the personal conduct policy to six games. After a video of the punch became public, Rice was released by the Ravens and Goodell suspended him indefinitely.Rice and the union contended he was essentially sentenced twice, and Jones agreed, saying Rice did not lie to or mislead the NFL.Petersons appeal of a league suspension lasting until next April 15 was heard by Harold Henderson last week. Henderson, a former NFL executive, was appointed by Goodell to rule on the appeal and is expected to do so soon.Peterson is seeking reinstatement, something Goodell said he would not consider before April 15.The 2012 NFL MVP hasnt played for the Minnesota Vikings since Week 1 after he was charged with child abuse in Texas. He was placed on paid leave while the legal process played out, and he pleaded no contest Nov. 4 to misdemeanour reckless assault for injuring his 4-year-old son with a wooden switch.___AP Pro Football Writer Barry Wilner and Sports Writers Simmi Buttar and Ronald Blum contributed to this story.___AP NFL website: www.pro32.ap.org and www.twitter.com/AP_NFL Omar Gonzalez Jersey .
