求翻译：The legal profession's return wasmarked by the renewed efforts of church and state to regulate it. In 1231 twoFrench councils mandated that lawyers had to swear an oath of admission beforepracticing before the bishop's courts in their regions, and a similar oath waspromulgated by the papal legate in London in 1237. During the same decade,Frederick II, the emperor of the Kingdom of Sicily, imposed a similar oath inhis civil courts.[199] By 1250 the nucleus of a new legal profession hadclearly formed. The new trend towards professionalization culminated in acontroversial proposal at the Second Council of Lyon in 1275 that allecclesiastical courts should require an oath of admission.[201] Although notadopted by the council, it was highly influential in many such courtsthroughout Europe.[201] The civil courts in England also joined the trendtowards professionalization; in 1275 a statute was enacted that prescribedpunishment for professional lawyers guilty of deceit, and in 1280 the mayor'scourt of the city of London promulgated regulations concerning admissionprocedures, including the administering of an oath.是什么意思？
