4. In the state of Hawaii, a person must meet certain educational requirements and pass a written exam to be granted a license to practice architecture. Once the initial license is received, an annual license fee is required to maintain the license. Wilson was granted an architecture license and paid the first annual fee. One year he failed to pay this fee. During this time, he contracted with clients for approximately $34,000 of architectural services. The defendants refused to pay the bill because Wilson had not renewed his license. Wilson sued for his fees. Could he collect even though he had not renewed his license? (Wilson v. Kealakekua Ranch, Ltd., and Gentry Hawaii, 551 P.2D 525)
