The former Atlanta City Council president says Mayor Andre Dickens' appointment of an interim inspector general was illegal.

Judge Ladawn "LBJ" Blackett has been appointed to oversee the office while the city works to establish a permanent replacement.

Just days after Shannon Manigault resigned, a new head of the Atlanta Inspector General's Office has been named.

ATLANTA — Atlanta Mayor Andre Dickens is appointing an interim leader for the Office of the Inspector General, city leaders said on Friday. Former Atlanta Inspector General Shannon K. Manigault announced her resignation earlier this month and accused City Hall leaders of creating a retaliatory work environment.

Mayor Andre Dickens has appointed Judge LaDawn "LBJ" Blackett as the interim inspector general for the Office of the Inspector General.

Shannon Manigault, the previous inspector general, resigned after the City Council claimed that the Office of the Inspector General (OIG) issued subpoenas that violated Georgia code.
