((2)) The Attorney General shall not file a motion to intervene under paragraph (1) before 90 days after the commencement of the action, except that if the court determines it would be in the interests of justice, the court may shorten or waive the time period.

((i)) the alleged conditions which deprive rights, privileges, or immunities secured or protected by the Constitution or laws of the United States and the alleged pattern or practice of resistance to the full enjoyment of such rights, privileges, or immunities;
((ii)) the supporting facts giving rise to the alleged conditions, including the dates and time period during which the alleged conditions and pattern or practice of resistance occurred; and
((iii)) to the extent feasible and consistent with the interests of other plaintiffs, the minimum measures which the Attorney General believes may remedy the alleged conditions and the alleged pattern or practice of resistance; and
((B)) that the Attorney General believes that such intervention by the United States is of general public importance and will materially further the vindication of rights, privileges, or immunities secured or protected by the Constitution or laws of the United States.

Nothing in this subsection precludes the award of attorney’s fees available under any other provisions of the United States Code.
