He became an associate justice of the Supreme Court of the Philippines on November 21, 2012 – the second youngest jurist to hold the said position and the youngest after Manuel V. Moran in 1938.

Leonen has been called, "The Great Dissenter" of the Supreme Court, often standing close to liberal and human rights-oriented decisions against the conservative bench close to Rodrigo Duterte and related dictatorial beliefs.
