A judge says he will rule later on whether a new law can be applied retroactively to Alabama's prepaid college tuition plan. Montgomery County Circuit Judge Johnny Hardwick heard arguments from both sides Monday and took the case under advisement. At issue is a settlement the board of the Prepaid Affordable College Tuition plan reached with many participants to pay less than full tuition because of the plan's financial problems. The Alabama Supreme Court ruled in March that the settlement violated state law. The Legislature revised the law in April.
