The first major overhaul of the Alabama ethics law in more than a decade could still happen during this legislative session, but time is short for a bill that was still going through changes on Monday.

The Alabama Senate Judiciary Committee is scheduled to hold a public hearing Tuesday on HB227 by Rep. Matt Simpson, R-Daphne, to repeal and replace the ethics law, which is intended to prevent public officials from using their offices for personal gain.

The rewrite of the ethics law is one of the key bills that still has a chance to pass during the final three days of the legislative session, which resumes Tuesday.

Sen. Sam Givhan, R-Huntsville, is expected to introduce a substitute version of the bill that passed the House. Givhan said Monday morning that the bill is still undergoing changes and he was not in a position to answer questions about it.

The House of Representatives passed Simpson’s bill on April 2. Simpson said it would clarify and strengthen a law that he said directly applied to about 300,000 elected officials and public employees, including teachers, police, fire fighters, and others who work for state and local governments.

Attorney General Steve Marshall and Ethics Commission Executive Director Tom Albritton opposed Simpson’s bill, saying it would weaken the law.

The bill would be the first major changes to the ethics law since reforms passed by a newly elected Republican majority in the State House in 2010. Alabama’s appellate courts have urged the Legislature to clarify some parts of the law.

While the ethics bill will attract attention on Tuesday, the biggest question still pending for the session is the fate of a proposed constitutional amendment to authorize a state lottery and seven new casinos. That bill, HB151 by Rep. Chris Blackshear, R-Phenix City, failed by one vote in the Senate last week.

There is a chance the bill could come up for another vote. Approval by the Senate would put the amendment on the ballot for voters on Aug. 20.

Other unfinished business includes final approval of the education and General Fund budgets for next fiscal year, which begins Oct. 1. Both budgets have passed the House and Senate and legislators need to reconcile the differences and send them to the governor.

The education budget calls for spending $9.3 billion from the Education Trust Fund, a 6.25% increase over this year. It increases starting teacher’s pay to $47,600 – the highest among neighboring states.

The state General Fund budget allocates $3.4 billion to non-education government services next fiscal year, including Medicaid, prisons, and mental health. The budget is $360 million more than the current fiscal year.

Other bills that could pass in the final days

HB130 by Rep. Mack Butler, R-Rainbow City, would expand a ban on classroom instruction or discussion about sexual orientation and gender identity in public schools. The ban now applies from kindergarten through fifth grade. HB130 would extend it through eighth grade. It would also prohibit teachers and other school employees from displaying a flag or insignia representing sexual orientation or gender identity in a classroom or on school property, such as a pride flag or rainbow flag.

HB111 by Rep. Susan DuBose, R-Hoover, would specify that male and female are defined in Alabama based on biological sex at birth and not based on gender identity. Sen. April Weaver, R-Brierfield, is sponsoring the bill in the Senate. DuBose said the purpose is to protect the privacy, fairness, safety, and equal opportunity for women and girls in sports and other areas.

HB385 by Rep. Arnold Mooney, R-Shelby County, would make school and public library staff criminally liable for distributing “sexual or gender oriented material” to minors without parental consent. It would force school and public librarians to remove a book that someone finds obscene or harmful to minors within seven days of written notice to the library director or principal or face misdemeanor charges.

HB36 by Rep. Phillip Ensler, D-Montgomery, would create a state law against devices that convert semi-automatic handguns to automatic fire, like machine guns. Sheriffs, police, and prosecutors came to the State House to urge legislators to pass the bill to ban the so-called Glock switches, which are illegal under federal law.

HB346 by Rep. Cynthia Almond, R-Tuscaloosa, would set up a tax credit program intended to provide incentives for developers to build more affordable housing. The bill is part of a “Working for Alabama” package of legislation intended to help more people work, bills that came in response to the state’s low workforce participation rate, one of the lowest in the country. Almond said the housing tax credits would complement a federal program that has been in place since the Reagan administration but that Alabama does not take advantage of.

Another bill in the “Working for Alabama” package is HB358 by House Minority Leader Anthony Daniels, D-Huntsville. It would provide tax credits to employers for their investments in child care centers for their employees, tax credits to private child care centers, and grants to nonprofit centers to expand or make improvements. Supporters of the legislation say Alabama has a shortage of affordable, quality childcare options, making it harder for some parents, especially single mothers, to work or return to work.

The House begins meeting at 1 p.m. on Tuesday, while the Senate begins at 2 p.m. Lawmakers have used 27 of the maximum 30 meeting days allowed for the annual session.
