The woman behind France's answer to the #MeToo campaign exposing male abusive behavior on Wednesday faces the verdict in a defamation case brought by a media executive she accused of making lewd and sexist remarks.

Sandra Muller started a viral hashtag in French in October 2017, #balancetonporc ("expose your pig"), which called on Frenchwomen to name and shame men in an echo of the #MeToo movement that began in response to allegations that toppled movie producer Harvey Weinstein.

In another post sent hours later, the U.S.-based French journalist had accused French TV executive Eric Brion of humiliating her with sexual remarks at a function in the town of Cannes in 2012.

Brion, a media consultant and former head of TV channel Equidia, acknowledges making inappropriate remarks for which he had apologized by text message the day after.

But he also claims that Muller's post wrongly portrayed him as a sex offender and the publicity around the incident has ruined his career.

In the civil suit, Brion is asking for 50,000 euros (55,000 U.S. dollars) in damages, 15,000 euros in legal fees (16,500 U.S.dollars) and the deletion of the tweet mentioning his name.

Muller, who works for a French media industry publication, wrote on her Twitter account that the verdict would be announced at 1300 GMT and she would hold a news conference at her lawyer's office half an hour later.

When the hearing opened in May, Brion's legal team defended his "right to flirt."

Muller, for her part, defended her right to freedom of expression and said her tweet meant sexist insults would be taken seriously.

In her Twitter post, she told of how Brion had humiliated her at the function, saying: "You have big breasts. You are my type of woman. I will make you orgasm all night."

The post led to an outpouring of tales of harassment and assault, which were hailed as helping to confront a culture of permissiveness in France towards unwanted advances.

But there has also been controversy, with a group of prominent French women led by film star Catherine Deneuve complaining that the campaign had become "puritanical" and defending the right of men to "hit on" women.

In a column in Le Monde newspaper late last year, Brion admitted making "inappropriate remarks to Sandra Muller" at a cocktail party.

But he also accused Muller of "deliberately creating ambiguity about what happened" by linking it to the response to the Weinstein affair.
