Enforcing Noncompetition Agreements is Tricky Business

Any business owner should keep abreast of laws and court rulings that can affect the way they conduct their operation and interact with employees. The law constantly evolves, and that is why our lawyers are vigilant in tracking changes that affect our clients. Citadel Investment Group v Teza Technologies is one such ruling that provides clarity regarding noncompetition agreements between employees and employers.

In this case, Defendants Malyshev and Kohlmeier worked for Plaintiff Citadel Investment Group until February of 2009, when they resigned. When Malyshev and Kohlmeier were initially hired by Citadel, they each signed a nondisclosure agreement and an employment agreement containing a noncompetition clause. The noncompetition clauses contained language giving Citadel the discretion to set the length of the restrictive period at zero, three, six, or nine months. Citadel elected for a nine month restricted period for both Malyshev and Kohlmeier upon their resignation.

Malyshev and Kohlmeier formed Defendant Teza Technologies two months after leaving Plaintiff Citadel in April of 2009. When Citadel discovered the existence of Teza and its status as an entity performing similar high frequency trading in July of 2009, the present legal proceedings began. Plaintiffs initially sought a preliminary injunction against Defendants based upon the noncompetition agreements signed by Malyshev and Kohlmeier. This injunction was granted in October 2009 for relief through November of 2009. The trial court made its decision based upon the agreed upon nine month period contained in the noncompete and calculated the time from February of 2009 when Malyshev and Kohlmeier resigned.

Citadel appealed the decision, and asked the appellate court to grant the injunction for nine months from October until July of 2010. Citadel argued that they had not received the benefit of the restricted period prior to the preliminary injunction being entered, and the Court should adjust the start date of the restricted period accordingly. The Court did not find the Plaintiff’s argument persuasive and denied the appeal because the plain language of the agreements signed by Malyshev and Kohlmeier contained no provision allowing for an extension of time or modification of the commencement date. Thus, the restrictive covenant properly ended in November as was required by the agreement signed by both parties.

Citadel Investment Group v. Teza Technologies serves as a warning to business owners who utilize noncompetition agreements and a potential boon to employees who sign them.
