Wilkins, a resident of and licensed by the State of Texas as a certified public accountant (CPA), rendered service in his professional capacity in Louisiana to Coverton Cosmetics Company. He was not registered as a CPA in Louisiana. His service under his contract with the cosmetics company was not the only occasion on which he had practiced his profession in that State. The company denied liability and refused to pay him, relying upon a Louisiana statute declaring it unlawful for any person to perform or offer to perform services as a CPA for compensation until he has been registered by the designated agency of the State and holds an unrevoked registration card. Provision is made for issuance of a certificate as a CPA without examination to any applicant who holds a valid unrevoked certificate as a CPA under the laws of any other State. The statute provides further that rendition of services of the character performed by Wilkins, without registration, is a misdemeanor punishable by a fine or imprisonment in the county jail, or both. Discuss whether Wilkins would be successful in an action against Coverton seeking to recover a fee in the amount of $1,500 as the reasonable value of his services.
