A French former priest accused of sexually abusing around 75 Boy Scouts has gone on trial, but the proceedings were delayed for a day because of a strike by lawyers.
It is France's worst clergy abuse case to reach court so far, and its repercussions reached all the way to the Vatican.
Bernard Preynat admitted in the 1990s to abusing boys, but was only removed from the priesthood last year.
The church defrocked him in July, after French Cardinal Philippe Barbarin was convicted of covering up for Preynat's actions.
Several other church officials were also accused of failing to alert police or prosecutors of his actions, including a senior Vatican official, Cardinal Luis Ladaria.
The Vatican shielded Cardinal Ladaria from trial, invoking his immunity as an official of a sovereign state.
Preynat, now 74, appeared in court on Monday in Lyon on charges of sexual assault of 10 minors between 1986 and 1991.
He faces up to 10 years in prison if convicted.
Preynat is also accused of abusing dozens of others in the 1970s and 1980s, but those alleged incidents happened too long ago to prosecute.
The judge delayed the hearing until Tuesday because of a strike by lawyers angry over President Emmanuel Macron's planned overhaul of the French pension system.
