I printed out the whole 69 pages of the Iowa Supreme Court decision that makes gay marriage a right in the state of Iowa. All I can tell you so far is that it's very pleasant reading, with the Iowa Supreme Court agreeing with a lot of good points by the gay plaintiffs who won, while discarding the stupid arguments of the gay-haters who lost.
Interestingly for people interested in legal standards, the ruling applies "strict scrutiny" to some issues and "intermediate scrutiny" to others.
For those who haven't read the ruling, basically it describes how the court arrived at its conclusion, and that makes it pretty fascinating.
If only because decisions from one state can be considered informative in other jurisdictions, this decision is good news all around.
