This report from the Office of Legislative Research (OLR), 2019 Bill Tracking:

"...identifies bills considered during the General Assembly’s 2019 regular session whose content or concepts were incorporated into other legislation, under different bill numbers, that the legislature passed.

It lists bills that were, at a minimum, fully drafted and had a public hearing but whose substance, in part or in whole, was enacted as a public act through separate legislation. The report includes those acts that (1) borrowed specific content from another bill or (2) addressed similar concepts using language that did not exactly match that of the other bill."
