Robert Kraft\'s attorneys contend officers violated the U.S. and state constitutions and used tactics normally reserved for serious crimes rather than low-level offenses.
Kraft\'s attorneys allege police misrepresented evidence to obtain a search warrant that allowed them to secretly install video cameras at the Orchids of Asia Day Spa. Police say those cameras recorded Kraft twice paying for sexual acts with spa employees.
The attorneys want all evidence collected against Kraft thrown out.
The case could be dismissed if they are successful. Kraft has pled not guilty but he issued an apology last month.
Kraft was charged in February with paying for sex acts at the spa twice in January.
