Select BSKS Experience

  • Aggressively investigated and successfully defended false and frivolous sexual assault claims against multiple clients, including a multinational conglomerate.
  • Represented the CEO of a publicly-traded, specialty finance company in connection to one of the largest and first-of-its kind, federal grand jury investigations in the investigating district. The U.S. Attorney’s Office declined prosecution, and the ensuing civil and SEC matters settled.
  • As co-counsel, successfully defended a day trader from prosecution for tax offenses stemming from inaccurate reporting by a brokerage clearinghouse. The client had been represented by prior counsel without resolution.
  • Successfully completed an internal investigation of a vending machine company entangled in a nationwide, multi-agency operation against business opportunities, and presented findings to the U.S. Department of Justice’s Consumer Branch Division, which resulted in a resolution of the case for the successor company and the non-prosecution of the individual clients.
  • Maria managed the day-to-day preparation for one of the most complex financial crimes charged in the Southern District of New York, involving interest-only strips, the Libor rate, and hedging strategies. This included supervising the review of the more than 3 million pages of discovery produced to the government by 33 different sources. Maria assisted with creating a trial database used to prepare for the cross-examination of 95 prospective government witnesses. She identified more than 347 potential defense exhibits to be compiled, 112 defense fact and character witnesses to be interviewed, and worked closely with various consultants and experts in formulating the defense strategy. The client received a 4-year sentence following the government’s pursuit of a 27-34 year sentence.
  • After uncovering misconduct by the lead case agent, the government agreed to forego criminal charges against the founder of a global ministry.
  • Joining partners Roy Black, Scott Kornspan and Mark Shapiro, in addition to outside co-counsel, Maria proved instrumental in securing a full declination of all criminal charges for the world’s second largest, publicly-traded employer under investigation for 800 RICO Act violations and fraud by the Miami-Dade County State Attorney’s Office.
  • Along with co-counsel, obtained an administrative stay, warding off the emergency suspension of a regulated business in a case involving one of the nation’s largest wholesale pharmaceutical distributors. Their owners were charged in a massive, 286-count indictment alleging nine schemes. The administrative stay was granted while simultaneously preparing for the megatrial.
  • Bargained reduced charges for the spouse of a former Florida State Senator, who was prosecuted as a co-conspirator in a $15-million Medicare fraud case. Felony charges were reduced to a single misdemeanor with no jail time, permitting the spouse to remain as special caretaker.
  • Served as co-counsel in the tax evasion case of internationally renowned artist Peter Max. Two days before opening statements in Mr. Max’s conspiracy and tax fraud case, a plea agreement was struck, allowing Mr. Max to serve two months in work-release, perform community service, and pay a $30,000 fine. Mr. Max faced a maximum of ten years imprisonment and a $500,000 fine.
  • Represented numerous business executives, including former WorldCom CFO, Scott D. Sullivan, and Robert Perlmutter, the founder of the nationwide chain Pearl’s Arts & Crafts. Both Messieurs Sullivan and Perlmutter’s cases resulted in significantly reduced charges and sentences, allowing them to reunite with their families and resume their normal lives.
