translate English to French: There is another common thread to the cases referred to: that is to say the lack of, or insufficient, control by the qualified institutions: central banks, stock exchange monitoring commissions, credit institutes, professional inspection bodies.
Un autre point commun à toutes ces affaires est l’absence ou l’insuffisance de contrôles par les institutions compétentes: banques centrales, commissions de contrôle des opérations boursières, institutions de crédit, organismes professionnels d’inspection.
