Head of the Judicial Inspection Authority Judge Barkan Saad has referred Mount Lebanon Prosecutor Judge Ghada Aoun to a disciplinary council.
Barkan claimed that Aoun had travelled to France "without an official authorization."
He also accused her of giving "offensive" testimonies against Lebanese judges.
"I was surprised with the decision," Aoun said, as she added that she had called Justice Minister Henry Khoury and submitted to him a travel permission request.
Aoun had travelled to France on Monday to participate in a conference about the victims of corruption and armed conflicts.
She said that she was proud of fighting corruption, asking for the help of Europe and France.
"Corruption is a result of impunity," she said, claiming that economists, banks and the central bank chief are supported by politicians and some judges.
"People with influence are not held accountable before the judiciary because they enjoy a political and judicial protection," she said.
Aoun had charged Central Bank Governor Riad Salameh with illegal enrichment and money laundering.
She also froze the assets of five of Lebanon's largest banks and those of their board of directors as she investigates possible transfers of billions of dollars aboard during the country's economic meltdown.
