Earlier this year, the Supreme Court of Indiana amended the Indiana Rules of Appellate Procedure to allow petitions to transfer to be filed up to 45 days after a decision is issued by the Court of Appeals.
The change takes effect January 1, 2019. My understanding is that the 45-day deadline will only apply to decisions handed down after January 1, 2019. If the Court of Appeals decided the case before January 1, 2019, the old 40-day deadline will still apply.
A copy of the rule change can be found here.
