'Justice' received generally positive reviews from music critics, with many praising Bieber's experimentation with new sounds and themes. The album debuted at number one on the US Billboard 200 chart and reached the top 10 in several countries, including Canada, Australia, and the UK.

: "Ghost" became a standout anthem for its relatable take on losing loved ones during the COVID-19 pandemic, balancing somber lyrics with an upbeat house-folk rhythm. Musical Style and Production Bieber moved away from the pure R&B of his previous album, , to explore a "poppier" sound.

This ambition is palpable from the opening seconds. The album begins not with a beat, but with a 43-second spoken-word intro by the late civil rights icon Martin Luther King Jr., taken from his 1967 “The Three Evils of Society” speech. It’s a jarring, sobering opener for a pop record, but it sets the table. Bieber isn’t just singing about heartbreak; he’s framing heartbreak within a larger context of societal fracture.

: Bieber stated his goal was to create music that provided comfort and made people feel less alone during a "broken" time on the planet.

Justice is noted for its high production quality, featuring contributions from heavyweights like , Benny Blanco , and Finneas .
