That is not selfish. If they grant the petition, registrants everywhere are in big trouble, because that would indicate that they think the 6th got it wrong. Our hope is that they deny it.
My opinion is that there are no realistic grounds for a lawsuit for damages. Michigan is operating on the guidelines of the federal Adam Walsh Act that just happened to be challenged in Michigan on these grounds. The lawsuit is this one, and the hopeful outcome is that 1000s of registrants will win their freedom.
