The legislation (HB 353), authored by Jack Thompson and legislator Mike Morle, recently swept the Utah House of Representatives by a 25 to four margin. According to GamePolitics, Jack Thompson claims the backers of the bill will seek an override of the veto.
In a letter explaining his reasons for the veto, Huntsman says HB 353 would likely "be struck down by the courts as an unconstitutional violation of the Dormant Commerce Clause and/or the First Amendment." Huntsman estimates that a possible "unintended consequence" of passing the legislation would be that the industries most affected could choose to forgo the use of "age appropriate labels on goods and services," because of their voluntary nature -- hurting families in the long run. Huntsman full letter can be read after the break.
Update: Michael D. Gallagher, president and CEO of the ESA has responded to the news in a comment, found after the break.
