1984 wasn't a successful year for Ligier with de Cesaris scoring all three points Ligier earned meaning the French team finished 9th in the Constructors Championship. De Cesaris actually scored the three points with a 5th place at the 2nd race of the season in South Africa and a 6th place two races later in San Marino.

The JS23 was replaced for the 1985 season by the Ligier JS25.
