Psi-Judges
Because of the Psi-Judges' special status within the Justice Department, they are entitled to more specialised equipment and procedures, such as the ability to carry silver boot knives (though Dredd was seen equipped with one and was considering recommending them as standard issue) and special silver tipped rounds for their firearms.
Like most other specialist Judges (i.e. Tek and Med), Psi-Judges do not wear badges with their surnames imprinted on them. Instead their badges simply read 'PSI'. This has been apparent in several comic strips featuring the Psi-Judges (although not in all of them, with some artists simply depicting the Judge's surname instead). However, their badges do have their surname imprinted in very small letters on the reverse.
Psi-Division also uses civilian auxiliaries and even prisoners to supplement its contingent of Judges, as anyone with psychic powers is potentially useful to Justice Department.
According to the Judge Anderson story "Lock In", Psi-Judges cannot use the same anti-aging treatments as street Judges do, due to its effects on psionic abilities. This is inconsistent with the artwork, however, which still depicts Anderson as if she is in her mid-twenties, when in reality she would be at least 48 years old.
