B.G. v. Board of Education of the City of Chicago

Ct. of Appeals issued reprimand to Appellee’s counsel for repeatedly submitting amended brief that contained changes to substance of original brief that was not authorized by Ct. of Appeals. While Ct. of Appeals had previously directed Appellee’s counsel to make changes to Appendix of brief, counsel could not make changes in other portions of brief, since, under Khan, 879 F.3d 838, both court and opposing counsel are entitled to rely on substance of original brief once it had been filed with court.
