Supreme Court Judge Alan Blow has been announced as Tasmania's new Chief Justice.
He will replace Ewan Crawford who will retire at the end of April.
He said Justice Blow was highly qualified to take on the new role.
"He's held many distinguished positions in a career spanning 40 years in the Supreme Court, both here in Tasmania and New South Wales."
He paid tribute to the retiring senior justices who prompted the shake-up.
"I'd also like to thank the retiring Chief Justice Crawford and Justice Peter Evans for the valued and enduring contribution they have made to Tasmania's justice system."
More than five years after missing out on a magistrate's position, Simon Cooper has now been appointed to the job.
The former Attorney-General Steve Kons was forced to resign from the frontbench after misleading Parliament about shredded documents recommending Mr Cooper's appointment as a magistrate.
The scandal lead to a shake-up of the protocols for hiring magistrates and judges.
Simon Brown was also appointed a magistrate.
