In October 1954 Laisant faced charges following the publication of a forceful poster calling for the ending of hostilities in Indo-China. The poster failed to include the requisite legal notice, and it had been printed on white paper. In February 1955 he was condemned by a Paris court and required to pay a large fine. One of those who spoke up for Laisant at his trial was Albert Camus, already an influential supporter of French liberal traditions.
