What to know about the electronic monitor a French court says Marine Le Pen must wear

Still, Le Pen said she’ll run for the French presidency next year despite that verdict — something that is possible under French law. She said she doesn’t expect to wear an electronic bracelet at all, because she believes France’s highest court will ultimately vindicate her on appeal.

That court, the Court of Cassation, previously said it would be able to rule before the presidential election, and Le Pen could eventually be forced to wear the monitor during the campaign if her appeal proved unsuccessful.

Here’s what to know about electronic monitors:

French prisons are overcrowded and have struggled with worsening detention conditions, according to the European Committee for the Prevention of Torture. Electronic monitors keep from adding to that problem.

Under French law, home detention requires a person to wear an electronic ankle monitor or bracelet and prohibits them from leaving their home or another designated location of residence, except during the hours authorized by the judge.

The designated location and the periods during which the person must remain there are determined by the court or by the judge responsible for the enforcement of sentences.

Such a device makes it difficult to conduct a political campaign but not impossible.

If Le Pen's conviction is eventually upheld, a specialized judge will decide how her electronic monitoring will be carried out, the residence where she must serve the sentence and the hours she will be permitted to leave.

The law provides that “during the period of sentence adjustment, the convicted person may be eligible for sentence reductions of up to six months per year," and even conditional release, the appeals court stressed in a statement.

France will hold the first round of its next presidential election on April 18, and if no candidate secures a majority of the votes, a runoff will take place two weeks later, on May 2.

“The appeals court has decided to make a (presidential) bid possible, so the decision must be respected,” said Céline Bertetto, president of the national association of sentence enforcement judges.

“Regarding sentence reductions: For a one-year sentence, there can be a six-month reduction, but she must comply with the permitted hours of movement and pay the criminal fine,” Bertetto added.

Le Pen backpedals on her plans not to run

A 57-year-old veteran of three presidential races, Le Pen repeated last week that she would not run for president next year if the appeals court ordered her to wear an electronic monitor.

Despite the ruling, she now believes that she won’t be subjected to monitoring at all.

“We are innocent of the acts we are accused of,” she claimed. "These acts cannot be classified as embezzlement of public funds.”

Sarkozy wore an electronic monitor

Former French president Nicolas Sarkozy wore an electronic ankle monitoring device last year after he was convicted to a year in prison in a corruption case. He was filmed leaving to go jogging with the device. He was granted conditional release, which allowed him to remove the electronic tag, after just over three months.

At the time, French media reported that he was authorized to leave his home between 8 a.m. and 8 p.m. This authorization was reportedly extended until 9:30 p.m. on Mondays, Wednesdays, and Thursdays, to make sure he could attend a separate trial.
