Comments:
Batman is the chairman of the JLA meeting in this story.

Snapper Carr is absent studying for and writing his college entrance exams during the stories in this issue and next.

The respective parallel worlds inhabited by the Justice League and the Justice Society are first referred to as Earth-1 and Earth-2 in this story. This two-part story also begins the annual tradition of a JLA-JSA team-up, usually containing the word "crisis" in the story title, which culminates in the Crisis on Infinite Earths series in 1985.

This story continues in Justice League of America #22.

Synopsis:
While the Justice League battles Felix Faust, Chronos, and Dr. Alchemy, who have united as the Crime Champions, they are unaware of a similar struggle taking place on the parallel world of Earth-2 between their counterparts, the Justice Society, and another team of Crime Champions composed of the Wizard, the Icicle, and the Fiddler. Having discovered the existence of the dual Earths, the two teams of villains have schemed to hide out on each other’s worlds after committing crimes. To safeguard their secret, they capture and imprison the two Flashes, who alone know of the alternate worlds and the method of traveling between them.

Disguising themselves as the Earth-1 villains, the Earth-2 Crime Champions battle and defeat the Justice League, magically trapping them in their Secret Sanctuary. The super-heroes use a crystal ball to contact the missing Flash, who tells them of his adventures on Earth-2, after which they summon the Justice Society to Earth-1.

The JLA then journey to Earth-2 while the two Green Lanterns race to free the captive Flashes, who are trapped in the transition zone between the Earths.
