The commissioner may issue a restricted license to a person:
(a) Who is or has been licensed under this chapter and who has been found by the commissioner after a hearing to have violated provisions of Division 4 of this code where such violation would justify the suspension or revocation of the license.
(b) Who is applying for a license under this chapter, who has met the examination and experience requirements, but who has been found by the commissioner after a hearing to have failed to have made a satisfactory showing that he meets all of the other requirements for the license applied for, where such failure would justify the denial of the license applied for.
