The AI legislation was one of several bills proposed during the short three-month legislative session that attempted to address major, weighty issues — from climate change to the codification of abortion rights in the state’s constitution. All failed after the Democratic-controlled General Assembly met its midnight adjournment deadline.

Lawmakers had some success stories this session, however.

Legislation cleared the General Assembly that makes numerous nursing home reforms, including prohibiting facilities from placing new residents in rooms with more than two beds.

Additionally, the Senate gave final legislative approval Wednesday night to a bill that attempts to address the proliferation of THC-infused beverages being sold in convenience stores and elsewhere. The legislation prohibits sales to anyone under 21 and allows the drinks to be sold only at packages stores or cannabis dispensaries, including those that sell both recreational and medical marijuana. Senators also voted to prohibit synthetic cannabinoids in cannabis and forbid the state’s licensed cannabis establishments from selling them.

Also late Wednesday, the Senate rushed to passed legislation that tightens absentee voting laws after people were captured on video last year stuffing reams of ballots into collection boxes in Bridgeport. The bill requires mandatory surveillance cameras at drop boxes and improved tracking of ballots, as well as new protections for poll workers.

“I don’t believe that it goes far enough,” Republican Sen. Rob Sampson said of the bill, calling what happened in Bridgeport a “fiasco” that warranted stronger action. He attempted to amend the bill with measures including a requirement that voters show an ID at the polls, but all four failed.

Lawmakers this session also passed a Democratic bill that updates Connecticut’s first-in-the-nation paid sick leave law from 2011 and requires all employers, down to those with a single worker, to provide their employees with time off by 2027. It awaits Lamont’s signature.

House Speaker Matt Ritter, a Democrat, noted how the sick leave bill came “close to the finish line” last year and benefited from lawmakers knowing what could pass this year. Other major bills didn’t have that advantage.

“There are just some bills you can’t do because of time,” he said.

Other high-profile proposals also failed Wednesday, including bills to curb the cost of e-books for libraries, expand protections for certain tenants, prohibit the sale of energy drinks to children, bar legacy admissions at public and private colleges, and provide Connecticut residents who telecommute for New York companies with a financial incentive to challenge their income tax bills from that state.

One reason why some concepts faltered this year, including a push to extend the state’s HUSKY health insurance program for immigrants over the age of 15, may be the Democrats’ unusual decision not to reopen the second year of the two-year budget passed last year.

Traditionally the short legislative session is dedicated primarily to adjustments to the second year of the budget.

Instead, late Tuesday, the Senate gave final legislative approval to a plan to spend at least $360 million in remaining federal COVID-19 pandemic funds on key areas, including higher education, not-for-profit social service agencies, municipal aid and children’s mental health. The same bill also granted Lamont expanded authority to move money between state accounts.

“When we agreed not to open the budget and did not do a budget, that really limited your options,” Ritter said.

Republican lawmakers strongly criticized the decision to not reopen the budget. Some predicted Connecticut will now face future deficits by using one-time COVID relief funds for operating expenses.

“The Democrats didn’t do their job on the budget and they’ve left the hard decisions up to the governor,” House Minority Leader Vincent Candelora said. Democrats dismissed the criticism.

In the final minutes of the session, Republicans in the Senate sharply criticized their Democratic colleagues for calling up a vague bill that creates a $3 million fund for low-wage workers, calling it a slush fund. While Democrats didn’t explain the intention of the bill, which passed with only Democratic votes, a coalition of unions later praised the legislation as a step toward creating an assistance fund for striking workers.
