Minneapolis City Council Member Andrew Johnson will step down Tuesday, and his successor, Aurin Chowdhury, will take over at that time.

The unusual transition — an early departure and swearing-in of a successor — is allowed under the city's charter, City Clerk Casey Carl has said. Chowdhury won the seat in last week's election.

Johnson, who was first elected in 2013, announced last year that he wasn't seeking another term. In September, he told constituents of the 12th Ward that he would step down before his term expires at the end of the year to begin work for a renewable energy investment firm.

Johnson started that job Oct. 10, and his involvement in City Council affairs has diminished since. He has been absent for most meetings except those of the full council.

The 12th Ward encompasses neighborhoods in the southeastern part of the city.

Chowdhury will take the oath of office prior to noon Tuesday, when Johnson's resignation becomes effective. She will serve out the remainder of Johnson's term, and then she and the other 12 council members will be sworn in Jan. 1 to serve two-year terms.

It's unclear if the early transition might have an immediate effect on any council actions.
