Central 46

The is an organization that serves as the judiciary authority of the Soul Society. Operating under a mandate from the Soul King, the influence Central 46 goes well beyond the boundaries of a judiciary authority and into those of legislative and operative authorities.

Overview
The Central 46 is comprised of forty wise men, gathered from all over the Soul Society, and six judges. These men are in charge of trying all Shinigami crimes, whether they were committed in Soul Society or the Human World. The Central 46 are also within their jurisdiction to order the use of deadly force by the Gotei 13, the Onmitsukidō or the Kidō Corps. Once a decision has been made, it is never overturned. While Soul Society has its own royal family and king, they reside within a distinct dimension outside of Soul Society and their rule is not felt by Soul Society's residents. The Central 46 receive a mandate from the Soul King to act in his place and so are considered for all intents and purposes as the royal and the ruling class of Soul Society. However, the Central 46 have no jurisdiction over the Royal Guard or the Shin'ō Academy. Upon their deaths at the hands of Sōsuke Aizen during the Ryoka Invasion, Captain-Commander Yamamoto has taken over their normal duties. Some time later, the Central 46 is reassembled and is shown performing its judiciary duties.

After the Wandenreich's attack on Seireitei and the death of Captain-Commander Yamamoto, the Central 46 appoints Captain Shunsui Kyōraku to take over the position of Captain-Commander of the Gotei 13 and be the new captain of the 1st Division. When Kyōraku later meets with the Central 46, they debate and argue with his decisions to have both Nanao Ise and Genshirō Okikiba serve as co-lieutenants as well as his first major decision as Captain-Commander to have Captain Kenpachi Zaraki trained in Zanjutsu. They ultimately have no choice but to accept Kyōraku's decision, given the preexisting rule of Gotei 13 captains being allowed to appoint their lieutenants and because of Soul Society's current inability to survive yet another invasion by the Wandenreich.

Residence
The residencial district of the Central 46 is an enclave in Seireitei called inside the Central 46 Compound. This enclave is forbidden for entry to anyone, regardless of their military or civilian status.

Proceedings
The proceedings take place in the underground assembly hall within the Central 46 Compound. Each of the Central 46 has a plaque with a number on it obscuring his face. These plaques are the only means to identify individual members. Investigations will be held by the Onmitsukidō in secret, at the behest of the 46. Defendants will not be told exactly what it is they are accused of until sentencing, nor what the source of the accusation was; they are only allowed to speak when they answer the questions addressed to them and will only rarely, if ever, given a chance to speak for themselves. The evidence is deemed far more important than any testimony. The Central 46 has very little patience to breaches of protocol. Wanton disregard for the proceedings or contempt of the Central 46 will more than likely bring added charges or sentence.

Other Rulings

 * Nest of Maggots: Detention in the Nest of Maggots is a punishment less known among the citizens of Soul Society and even the ranks of Shinigami. It is commonly reserved for high-level Shinigami who have either broken the law, quit the Gotei 13 or were otherwise deemed dangerous and mentally unstable (as per the government's interpretation). One well known inmate of the Nest of Maggots was Mayuri Kurotsuchi. The sentence is carried out by the detention unit of the Onmitsukidō, formerly headed by Kisuke Urahara.
 * Spirit-Sealing Pit: The spirit-sealing pit is an ancient form of execution in which Shinigami criminals are thrown into a pit walled with Sekkiseki – a type of stone that absorbs spiritual power, preventing those nearby from using their powers. Hollows are then thrown into the pit with the criminals as the means of execution. The practice was considered too barbaric and was discontinued. The pits themselves were converted into garbage dumps.
