Hat tip to Sarah Johnson, who forwarded info about State v. Cox, No. 07–2083 (Iowa April 30, 2010), where the Iowa Supreme Court holds that a state statute that allows introduction of propensity evidence in sex offense prosections violates the state constitution's due process clause.

There is a lot of great langauge in this decision regarding the pernicious effect of prior bad acts evidence that might be useful in a Kansas case dealing with typical prior-bad acts evidence.

Here is coverage on Simple Justice, which in turn links to coverage of the case on The Volokh Conspiracy.
