Experience Highlights

Representative Matters

  • Cassandra represented a B2B technology provider in a dispute with a former executive over a financing transaction. The former executive filed a lawsuit in federal court alleging violations of the Securities Act and the Securities Exchange Act in connection with his participation in the transaction. Cassandra successfully moved to dismiss all claims and in December 2023 obtained the first federal decision interpreting accredited investor status within the context of the definition of an executive officer.
  • On behalf of a multi-state hotel and resort developer, Cassandra successfully reversed a contempt order. Prior to her involvement in the case, a former investor commenced judgment enforcement proceedings and sought discovery against both the developer and its principals. The investor obtained a contempt order against the principals for failing to produce financial information. After being retained, Cassandra filed a motion for reconsideration of the contempt order on the basis that the principals were not the proper subjects of discovery within the scope of the contempt order as they were not parties to the case and had never been properly subpoenaed. The court agreed and reversed the contempt order against the principals.
  • Cassandra represented the owners of a landmarked property against their billionaire neighbor for breach of a license agreement in a multiparty case defended by eight law firms in New York State Supreme Court Commercial Division. She obtained a temporary restraining order preventing a sale of the neighboring property pending litigation and obtained summary judgment on multiple claims including specific performance, indemnification, strict liability and private nuisance.
  • In a federal court action to collect unpaid invoices for a B2B service provider in a matter involving wire fraud, Cassandra litigated against an AmLaw 100 firm and collected a significant percentage of the claim.
  • Cassandra defended a textile manufacturer in a B2B breach of contract action.  She successfully moved to vacate a default judgment that had been entered prior to her involvement in the case.
  • Cassandra represented an investment bank in a consolidated class and derivative multi-party action in connection with the provision of a fairness opinion on a merger. She and her team successfully obtained dismissal of multiple claims against the client.
  • In putative class action cases consolidated into a multidistrict litigation, Cassandra defended a nationwide accounting firm on claims including fraud, professional negligence and unjust enrichment in connection with certain tax shelter plans. Cassandra and her team obtained dismissal of numerous claims and she then successfully obtained reconsideration of the court’s prior decision not to dismiss the claim for punitive damages, setting the case up for a favorable settlement.
  • Cassandra represented an investor in a biotechnology fund in a federal lawsuit against beneficial owners of more than 10% of company stock for disgorgement of short-swing profits prohibited under the securities laws. Defendants were represented by one of the top 15 largest global law firms and argued for dismissal on the basis that they were subject to an investment advisor exemption from the short-swing trading rules. Cassandra discovered through research that the Defendants were activist investors and successfully defeated the motion to dismiss on the basis that the Defendants did not qualify for the investment advisor exemption as activist investors.
  • On behalf of a New York City-based brokerage handling billions in assets, Cassandra successfully obtained summary judgment for the full amount of the claim in New York State Supreme Court Commercial Division in connection with a multimillion-dollar breach of contract. Cassandra then defeated a motion before the Appellate Division to stay execution of the judgment pending appeal.
