Most of Indiana's new/amended laws become effective in July. Very few have a January effective date and I don't know of any this year.
Is there a website listing all/any news laws that took effect January first?
Promulgation. Promulgated. Promulsified?
That would be zero, but come June 30th I would check Indiana Lawyer or Indiana Law Blog. Both usually do a "new laws" post.
