Suffolk is currently scheduled to move from its existing two-tier local government structure (county, district and borough councils) to three new unitary councils, with implementation planned for April 2028 and elections for the new authorities expected in May 2027. SCC has decided to proceed with a legal challenge against the Government's decision regarding the proposed reorganisation. The decision follows an announcement made in May that the council intended to challenge the legal basis of the Government's plans.

The legal action has raised concerns among some councillors regarding potential costs to the public purse and the possible impact on preparations for the planned transition to the new unitary authorities. Supporters of the challenge argue that it is important to test the legal basis of the Government's decision before the reorganisation proceeds.
