Mich. Comp. Laws § 722.674: Additional definitions.

Sec. 4.

As used in this part:

(a) "Harmful to minors" means sexually explicit matter that meets all of the following criteria:

( i ) Considered as a whole, it appeals to the prurient interest of minors as determined by contemporary local community standards.

( ii ) It is patently offensive to contemporary local community standards of adults as to what is suitable for minors.

( iii ) Considered as a whole, it lacks serious literary, artistic, political, educational, and scientific value for minors.

(b) "Local community" means the county in which the matter was disseminated.

(c) "Prurient interest" means a lustful interest in sexual stimulation or gratification. In determining whether sexually explicit matter appeals to the prurient interest, the matter shall be judged with reference to average 17-year-old minors. If it appears from the character of the matter that it is designed to appeal to the prurient interest of a particular group of persons, including, but not limited to, homosexuals or sadomasochists, then the matter shall be judged with reference to average 17-year-old minors within the particular group for which it appears to be designed.
