Here, plaintiff s cover letter cites his experience in engineering, including design, product development, failure analysis, and investigative procedure, and boasts of his involvement in a case in which he determined the cause of the failure of a truck seat. Plaintiff s resume reiterates much of this, lists his educational exploits and employment history, and accentuates his forensic work and industrial failure investigations. In these two documents, plaintiff clearly holds himself out as able to perform many services recognized as professional engineering practices, especially forensic engineering. We conclude that the Department did not err in finding that plaintiff violated the Act by offering to practice and practicing professional engineering as shown in plaintiff s cover letter and resume. Plaintiff next contends that the Department s order is an invalid prohibition of protected speech.
Commercial speech is subject to state regulation.
Such speech may be regulated by means of appropriate time, place, and manner restrictions and where such speech is false or misleading or related to unlawful activity. 171 Ill. 2d at 518. Where a particular content or method of advertising suggests that it is inherently misleading or where experience has shown that such advertising is subject to abuse, states may impose appropriate restrictions. While misleading advertising may be prohibited entirely, certain types of potentially misleading information may not be absolutely prohibited if the information may also be presented in a way that is not deceptive. Furthermore, the restriction must be in proportion to a substantial interest and be designed carefully to meet the State s goal.
