The defendants had been in custody since early January when police opened fire on protesting textile factory workers who were calling for a minimum wage of USD 160 a month to make clothes for brands including Gap, Nike and H&M.
They were sentenced to between one and four-and-a-half years in prison for charges relating to the unrest by the Phnom Penh Municipal Court today. The court suspended the remainder of the terms, meaning the 23 were able to walk free.
"While we welcome the release, we regret that they were convicted," said activist Am Sam Ath of local rights group Licadho.
The case has deepened concerns over the forceful reaction of strongman Hun Sen's regime to protest.
On Monday, representatives from brands including H&M, GAP, Puma and Levi's, along with the IndustriALL Global Union, met senior government figures to discuss the situation.
"For the first time global brands have acknowledged that they are prepared to cost in the price of higher salaries in Cambodia," said IndustriALL general secretary Jyrki Raina in a statement on Tuesday.
Cambodia's textile industry provides clothes and footwear for many in the West and employs some 650,000 local people.
Workers have staged months of strikes and street protest demanding better safety standards and a doubling of the minimum wage to USD 160 a month, or about USD 8 a day. So far the government has offered them USD 100.
The defendants today were greeted by several hundred supporters, including Buddhist monks, who cheered their release.
The court also handed suspended sentences to two other garment workers involved in November protests, when violent clashes between police and workers left one woman dead.
