Heading: Officer DeCianni

Text: Officer DeCianni also claims that he is entitled to qualified immunity on Gonzalo’s false arrest claim. Because Gonzalo claims he did not throw a beer can or bottle at Officer DeCianni, as Officer DeCianni claimed, a factual dispute exists as to whether Officer DeCianni had probable cause for arresting Gonzalo on that basis. Officer DeCianni, however, argues that he is nonetheless entitled to qualified immunity because he “could have legally arrested Gonzalo for failing to shut down the party (which was Gonzalo’s understanding as to why he was being arrested) and causing a disturbance; he could also have arrested him for resisting a lawful police order.” Appellant Brief at 31. “Whether an officer has probable cause to arrest depends on the requirements of the applicable state criminal law.” Pourghoraishi v. Flying J, Inc., 449 F.3d 751, 761 (7th Cir. 2006). In his brief on appeal, Officer DeCianni did not cite to the relevant Illinois statutory provisions that he claims justified his arrest of Gonzalo. Officer DeCianni also did not identify the state law requirements necessary to justify Gonzalo’s arrest on the proposed alternative grounds. Officer DeCianni’s failure to develop this argument constitutes a forfeiture of those arguments on appeal. J. S. Sweet Co., Inc., v. Sika Chem. Corp., 400 F.3d 1028, 1035 n.2 (7th Cir. 2005). Accordingly, we affirm the district court’s denial of summary judgment to Officer DeCianni on Gonzalo’s false arrest claim.
