Youras Ziankovich v. Colorado

Petitioner is a lawyer licensed by the State of New York and duly authorized to practice before the U.S Department of Homeland Security pursuant to the federal regulations. State of New York requires Petitioner to abide NY RPC while practicing in front of non-court federal agencies, such as DHS. Petitioner was never licensed or admitted in Colorado. However, Colorado Supreme Court suspended Petitioner's New York license for the violation of Colorado Rules of Professional Conduct while practicing before the U.S. Department of Homeland Security. State of New York found no violation of NY RPC in Petitioner's conduct. The question presented is whether Colorado violated Petitioner's constitutional rights through maintenance of the discipline proceeding.
