As most of the city population are students, it is the duty of Judgment to catch those delinquents misusing their powers along with other offenders and protect the students. They can arrest criminals, though only Anti-Skills can formally take them into custody.
In the event of a situation that Judgment members cannot handle, their superiors and the city's security forces, the Anti-Skills will take over. Overall, the role of a Judgment officer is more like a part-time civilian patrol officer and are often used in community services, such as cleaning garbage from the streets (when cleaning robots are unavailable), helping locate lost objects, traffic duty, etc.
Judgment is decentralized and its branches are autonomous between each schools, thus their authority are normally limited to their school grounds and districts; a Judgment member of another branch can request the Judgment branch that has control of an area to temporarily extend their jurisdiction in that area; also, they can only use their authority outside when ordered to by their superiors or in cases of emergency.
Joining Judgment's ranks requirement is only being an Academy City student, though it is unknown what the minimum age required is, as elementary students are allowed to join the ranks. Also, recruits need to pass 13 kinds of tryouts and training (which includes going to Judgment Training Center to train) lasting for 4 months, and sign 9 contracts, before formally becoming a member of Judgment. Academy City recruits Judgment twice a year, summer and winter.
Younger members of Judgment are partnered with older members to patrol the city, though when one reaches a certain age, a member is allowed to patrol alone or form partners with other members of the same branch. During large-scale operations, several members of Judgment of the same branch can form a group for patrols.
Other than the unique abilities of each individual, members of Judgment are trained on how to apply first aid. They are also probably trained in basic emergency situation responses, as well as basic physical training.
All members of Judgment are required to wear their armband, which bears the Judgment symbol, during operations; however, they can also keep it hidden, when they want to be discreet and don't want to draw attention to themselves.
Judgment members are equipped with handcuffs that are used for restraining criminals, some regular handcuffs, while there are others more complex like the Cuffs Grenades (
Officers also have access to a salve developed by Heaven Canceller, which is a type of gel that can quickly disinfect wounds, cease bleeding, and stop it from opening again. It's restricted to Anti-Skill and Judgment for use in combat situations, to quickly patch up most external wounds as first aid so you can resume combat.
They can also use signal flares, as to clear an area of civilians.
Judgment also has access to a variety of equipment in analyzing a crime scene. Other tech is available, like handheld devices looking like marble-sized balls and made to interfere with listening devices for security purposes. There is also a Judgment-exclusive phone map app, presumably more extensive and detailed than normal ones.
Unlike Anti-Skill, Judgment members do not carry firearms.
