SUTTON, Chief Judge. Dipendra Tiwari and Kishor Sapkota sought to establish a home healthcare company, called Grace Home Care, that would focus on serving Nepali-speaking individuals in the Louisville area. Like other companies that provide healthcare services, home healthcare companies face a number of regulations. One of them is a certificate-of-need requirement, which restricts the number of such companies that may serve each county in Kentucky. When the Commonwealth denied their certificate-of-need application, Tiwari and Sapkota filed this lawsuit. They claim that the regulation violates their Fourteenth Amendment right to earn a living, serves only the illegitimate end of protecting incumbent home healthcare companies from competition, and through it all lacks a rational basis. At the motion to dismiss stage, the district court allowed the case to proceed to discovery. On summary judgment, the district court upheld the law. We affirm.
