Plain English Breakdown

HB4018: Sheriff Authority Over Volunteer Groups

This law allows county sheriffs to use volunteer posse and reserve groups for official duties and gives the sheriff exclusive power to set rules for these groups' organization and equipment when they are activated.

What This Bill Does

  • Allows a county sheriff to request help from volunteer posse and reserve organizations in their county while performing official duties.
  • Gives the sheriff exclusive authority to regulate how these groups are organized and what equipment they use once the sheriff activates them.
  • Requires that volunteers follow written policies created by the sheriff's office when acting within the sheriff's authority.
  • Confirms sheriffs can authorize trained posse members to carry deadly weapons without a permit while on duty.

Who It Names or Affects

  • County sheriffs in Arizona
  • Volunteer posse and reserve organizations located within county jurisdictions

Terms To Know

Posse or Reserve Organization
A group of volunteers who assist the sheriff with official duties.
Exclusive Authority
The sole power to make rules and decisions about organization and equipment without sharing that control when activated by the sheriff.

Limits and Unknowns

  • Sheriffs can only regulate these groups' organization and equipment after activating them.
  • Regulations must be consistent with existing state laws.
  • The law does not specify a unique effective date, so it takes effect on the general effective date.

Amendments

These notes stay tied to the official amendment files and metadata from the legislature.

Plain English: This amendment gives county sheriffs the power to ask for and use help from volunteer posse and reserve groups while performing their official duties.

  • Sheriffs can now request aid from volunteer posse and reserve organizations located in their county.
  • When activated by a sheriff, these volunteers must follow rules set only by that sheriff regarding how they are organized and what equipment they use.

Plain English: This amendment rewrites the law to list all sheriff duties and gives sheriffs full control over volunteer groups, including allowing trained volunteers to carry guns without a permit.

  • It lists specific jobs for sheriffs like keeping peace, running jails, serving court papers, and leading search-and-rescue teams.
  • It states that the sheriff has executive authority to manage how any auxiliary, posse, or reserve volunteer group is organized and operates while helping the office.
  • It allows members of a volunteer posse who have passed approved firearms training to carry deadly weapons without a permit when they are on duty.
  • The text does not explain what specific rules or limits apply to how sheriffs manage these volunteer groups beyond saying it must be 'consistent with law'.
  • It is unclear if this change removes any existing powers that other agencies might have over these volunteers.

Plain English: This amendment changes the law so that sheriffs can ask volunteer posse and reserve groups for help with their legal duties, while giving the sheriff full control over these specific groups' organization and equipment.

  • Allows a sheriff to request and use help from volunteer posse and reserve organizations in the county for any lawful duty they perform under state law.
  • Removes 'affiliated auxiliaries' from the list of groups that a sheriff can regulate, meaning sheriffs no longer have authority over these specific auxiliary groups.
  • Clarifies that a sheriff has exclusive power to control how posse or reserve organizations are organized and what equipment they use when those groups are activated by the sheriff.
  • The text does not define exactly who qualifies as an 'affiliated auxiliary' versus other volunteer groups.
  • The amendment removes a section of the bill that was cut off in the provided text, so any changes to Section H or later parts cannot be explained.
