He was then an advocate of the crowning of Carol Caraiman as King of Romania (in the place of his underage son Mihai). In the autumn of 1927, while distributing Carol's appeals to the leaders of various political parties and carrying his letter to Queen Marie, he was arrested (martial law was proclaimed by the Ion I. C. Brătianu government in the incident's wake). Manoilescu, who benefited from Averescu's vocal support, was acquitted when tried by a court subordinated to the Council of War in late November.
