"It's something we've wanted for years," Linda Gobler, president and CEO of the Michigan Grocers Association, said in a Detroit Free Press report.
The new law would also permit the tasting of free samples of beer and wine, but would limit the number of two-ounce samples to three per patron.
"This will be great for Michigan wineries and breweries as they try to increase awareness of their products," said Andy Deloney, a spokesman for the Michigan Restaurant Association.
The new law would let restaurants and bars start selling alcohol at 7 a.m. Sundays. Current law prohibits liquor sales until noon on Sunday.
Additionally, liquor sales would be legal until 11:59 p.m. Christmas Eve, and again after noon on Christmas Day. The present law prohibits sales after 9 p.m. on Christmas Eve and all day Christmas Day.
