The governor's office said in a release that the injunction is needed "because of the imminent risk of irreparable harm created by the unlawful exercise of federal control of education in Louisiana."
The injunction would bar the state's Board of Elementary and Secondary Education from implementing any assessment program developed by the Partnership for the Assessment of Readiness for College and Careers, known as PARCC.
Louisiana students were set to take the PARCC test starting this upcoming school year, but educators have been in limbo since Jindal publicly began trying to get Louisiana out of the test this summer -- over the objections of state Superintendent John White and other state education officials.
Late last month, BESE voted to join a lawsuit suing the governor over the issue, claiming he was unconstitutionally meddling in the education board's work. Jindal fired back with a counter-suit of his own against BESE, saying the state's agreement with PARCC is unconstitutional and gives the group too much power to make state education decisions.
Jindal's new amended version of that lawsuit, filed Wednesday in 19th Judicial District Court in Baton Rouge, expands on that premise. In addition to adding the request for the injunction, the lawsuit claims the PARCC agreement violates federal law.
