There are two states that have two separate courts of last resort: Oklahoma and Texas. Both have a court of last resort for civil matters (Supreme Court) and one for criminal (Court of Criminal Appeals). Texas has debated and attempted for 20 years to merge their courts, now Oklahoma appears to be trying to do the same.
HJR 1051 as filed and approved by the House Rules Committee yesterday would abolish the Court of Criminal Appeals within one year of approval by voters. All “duties, powers, cases, records, property, and personnel” EXCEPT judges would transfer to the Supreme Court. It appears the judges of the Court of Criminal Appeals would simply have their existing offices and terms ended.
The last and only time in recent history an effort like this was attempted in 2012 (discussed here).
There has been a single attempt in the last 20 years to merge the two courts. SJR 83 of 2012 would have abolished the constitutional references to the Court of Criminal Appeals. This was part of a package of bills, including SJR 84 of 2012 which would have stripped the newly combined Supreme Court of the power to strike down any law as unconstitutional, instead allowing an “Ad Hoc Court of Constitutional Review” created by the legislature itself to determine whether its laws were constitutional.
