Last September, the NFL initiated legal proceedings against M.I.A. for her 2012 Superbowl halftime performance, during which the singer flipped up her middle finger to the camera. According to The Hollywood Reporter, the NFL is now seeking even more money from M.I.A. – $15.1 million to be exact – in “restitution.” This figure is estimated based on how much advertisers would’ve paid for ad time during the incident and is in addition to the $1.5 million the organization has been seeking from the singer for the past two years, for allegedly breaching her performance contract.

M.I.A. and her attorney Howard King have been vocal about fighting the lawsuit, and have even set up an email address for the public to submit their own claims of the NFL’s “lack of wholesomeness.” She and her legal team assert that this is an example of bullying by the NFL, and to “make an example of Respondents for daring to challenge NFL.” Not to mention that the singer has also consistently defended the act, stating it was a Hindu symbol in honor of goddess Matangi.

Her arbitration papers go on to also question NBC’s lack of activating the “5 second delay” system, claiming the broadcaster should also share responsibility in this situation:

“NFL, and NBC, failed to exercise ordinary care in the conduct of the Halftime show by not activating the ‘5 second delay’ system in place for the broadcast. Any alleged fault or liability of Respondents should be diminished by NBC’s dereliction. Discovery has not been taken yet to determine whether contractually NBC owed a duty to NFL to properly operate the delay system. Very likely that is indeed the case.”
