Why Courts Strike Down Non-Competes That Exceed Established Customer Radii

In 2024, a Texas appellate court reviewed a non-compete agreement that barred Rosa Barrett, a former chiropractic case manager, from working within a 500-mile radius of her previous employer's Houston clinic.[1]

The restriction spanned most of Texas, all of Louisiana, and significant portions of five other states and Mexico. The First Court of Appeals in Houston struck down the covenant entirely, ruling that the 500-mile boundary vastly exceeded Barrett's actual working territory.[1]

The court declared the restriction "broader than is reasonably necessary" to protect the employer's business interests. This ruling illustrates a definitive boundary in employment law: non-compete agreements face categorical invalidity under common law when their geographic restraints extend beyond an employer's established customer radius.[1][6]

While the Federal Trade Commission's nationwide ban on non-compete clauses was vacated by a federal district court in August 2024, state common law continues to govern these contracts. Without a federal prohibition, state law remains the primary source of rules governing employee non-competes.[2]

This shift has made compliance significantly more complex for multi-state employers, who must navigate varying judicial interpretations of what constitutes a reasonable territorial limit. "Courts do not enforce non-compete clauses automatically," notes DiliTrust's legal analysis.[2]

The Reasonableness Standard

Under common law across the United States, restrictive covenants are generally enforceable only if they meet strict requirements for reasonableness. Courts evaluate whether the restrictions are no broader than necessary to protect legitimate business interests, such as trade secrets or customer relationships.[3]

The duration and geographic scope of the agreement must be proportionate to the employer's actual business presence. When a geographic restriction is completely absent, courts often consider the omission patently unreasonable and invalidate the agreement entirely.[2][7]

However, defining a specific territory does not guarantee enforcement if the boundary overreaches the company's genuine market footprint. A valid non-compete must define exactly what activity is restricted, where it applies, and for how long the limitation lasts.[2][8]

Many enforceable non-competes fall within a duration of six months to two years, but permissible limits vary by jurisdiction and role. When paired with an overly broad geographic radius, even a short six-month restriction can be struck down as an unreasonable restraint of trade.[2][7]

Defining the Customer Footprint

Judges determine reasonableness by comparing the restricted area to the specific territory where the former employee actually operated. If an employee managed accounts exclusively within a single metropolitan area, a nationwide restriction is almost certainly overbroad.[2][8]

In Callahan v. L.G. Balfour, an Illinois appellate court examined a non-compete that barred an employee from working in Chicago and seven surrounding counties. The court found the eight-county limitation too large to be reasonable under the circumstances.[5]

The appellate judges stressed that such a restriction imposed an undue hardship on an employee with 30 years in the industry, who would have to relocate to comply with the agreement. The ruling highlights how courts weigh the employee's ability to earn a living against the employer's protective interests.[5]

Conversely, a 50-mile radius around a primary office in Tampa, Florida, is more likely to survive judicial scrutiny if it aligns with the employer's actual operations. Such a clause ties its restriction directly to the geographic limit where genuine competition occurs.[4]

The Burden of Proof

Employers bear the burden of proving that their geographic restrictions are necessary to protect their goodwill and proprietary information. In Fomine v. Barrett, the employer argued that the former employee's state-wide marketing efforts justified the massive 500-mile restriction.[1]

The Texas court rejected this argument, emphasizing that the geographic scope must be driven by data and facts regarding the employee's actual duties. Guesses or hypothetical expansions of the employee's geographic area of work are insufficient to uphold a restrictive covenant.[1]

When an employer fails to demonstrate a legitimate business interest, courts will rule in favor of the former employee, as seen in Reliable Fire Equipment Company v. Arredondo. In that 2011 dispute, two former employees started a competing fire alarm business after signing one-year non-competition agreements.[5]

The lower courts initially invalidated a restriction covering Illinois, Indiana, and Wisconsin, ruling that the employer failed to prove a legitimate business interest. Although the Illinois Supreme Court later overruled them based on the totality of circumstances, the case underscores the intense judicial scrutiny applied to multi-state boundaries.[5]

The Blue-Pencil Doctrine

When a court encounters an overbroad geographic restriction, the outcome depends heavily on the jurisdiction's approach to contract modification. Some states permit "blue-penciling," a judicial practice where the court narrows an unreasonably wide geographic boundary to make the clause enforceable.[2]

Under this doctrine, a judge might reduce an excessive 500-mile radius to a 50-mile radius rather than voiding the entire agreement. This allows the employer to retain some level of protection while relieving the employee of an undue geographic hardship.[2]

Other jurisdictions follow a strict "red-pencil" rule, where a single unreasonable provision invalidates the entire restrictive covenant. In Connecticut, the five-prong reasonableness test is disjunctive, meaning that an unreasonable geographic restriction alone can preclude enforcement of the whole contract.[7]

Geographical restrictions that go beyond what is required for fair protection of the employer are unenforceable on the grounds that they are unreasonable restraints of trade. A single unreasonable provision can be sufficient to invalidate the entire agreement in these strict jurisdictions.[7]

Industry-Specific Variations

The acceptable geographic radius often varies based on the specific industry and the nature of the employee's role. For a local service business, a five-to-ten-mile radius might be sufficient to protect customer relationships and trade secrets.[4]

In specialized medical fields, courts have sometimes enforced broader restrictions if the patient base is geographically dispersed. However, these exceptions are narrow and heavily dependent on the specific facts of the employee's daily activities.[8]

In Medtronic, Inc. v. Walland, a court applying California law ruled that enforcing a broad non-compete would effectively bar a specialist "from working anywhere else in the country that overlaps with his specialty." The court emphasized that geographic restrictions must coincide with the areas where the employee previously performed their activities.[8]

The rise of remote work has further complicated the traditional analysis of geographic restrictions in non-compete agreements. When an employee performs their duties online from a distant location, defining the employer's territorial footprint becomes legally ambiguous.[8]

Strategic Considerations for Workers

Employers are increasingly shifting toward non-solicitation clauses that target specific client lists rather than drawing arbitrary geographic circles. A restriction prohibiting sales to accounts managed during the last 12 months of employment is far more defensible than a blanket territorial ban.[2][4]

Employees facing broad non-compete agreements often assume the restrictions are ironclad, but legal vulnerabilities are common. Many companies draft unreasonably overbroad agreements, relying on the chilling effect to deter departing workers from joining competitors.[8]

Workers can negotiate the geographic scope before signing, requesting that the radius be limited to their specific sales territory or office location. Understanding these common law limitations empowers professionals to navigate career transitions without unnecessary geographic constraints.[4][6]
