What will the appeal process against Le Pen achieve?

Even Le Pen’s ineligibility to stand would not diminish the success of the far right, Libération concludes:

“Although a conviction would undoubtedly restrict Marine Le Pen’s personal freedom to act, the far right is unfortunately still doing well in the polls. This is evident from the success of Plan B – with Bardella, the successor to Jean-Marie Le Pen’s heiress. … If there are political consequences, these will affect the fate of the Le Pen clan, which has been at the forefront of the far right for decades and is now seeing the ground pulled from under its feet, just when the top step of the podium seems so close. … The judiciary would be merely an instrument of an irony of history that might raise a smile but is not really a cause for celebration, given that the RN – with or without Le Pen – plays such a major role in French politics today.”
