[5] Palmieri and his new ensemble (still similar to La Perfecta, with Barry Rogers being replaced by Lewis Kahn) recorded a series of four albums for Tico that have been said to contain his "best sounding" work.

[10] Musically, it has been described as "a composition in which the guaracha predominates within a multiform and polyrhythmic salsa", and its lyrics call for justice for "boricuas" (Puerto Ricans) and "niche" (African-Americans).

[8] Together with the title track, side A contains the more Latin-based pieces of the album, such as Rafael Hernández's bolero "Amor ciego" and Ignacio Piñeiro's son-rumba "Lindo yambú".

"Everything Is Everything" is based on a standard blues form, with strong North American influences and a rhythm section similar to that of the soul jazz groups of the 1960s.

[14] In the top left corner, a small picture of Palmieri sitting on the floor, "thinking, worrying", further reinforces the message of the album.

[14] On his book Latin Jazz, John Storm Roberts wrote a favourable review of Justicia, calling it "the beginning of a number of extraordinarily important Palmieri releases".

[12] Tony Wilds wrote a mixed review for AllMusic, describing the album as "interesting" but "only average for an Eddie Palmieri record, which is still heads above most, and probably essential listening".
