BATON ROUGE, La. (AP) -- Judge Michael Caldwell had ruled the legislation was unconstitutional because it bundled together too many items spanning Louisiana's education laws. But the Louisiana Supreme Court vacated Caldwell's decision and asked him to re-evaluate his ruling.

Caldwell heard new arguments Friday and said he'll issue his decision Jan. 8.

The Supreme Court said its opinion in a separate education case involving Jindal's statewide voucher program contains new case law for Caldwell to review. In that case, the high court rejected a similar argument that the voucher bill contained too many objectives.

The Louisiana Federation of Teachers filed the lawsuit challenging the 2012 law.
