Phoenix is suing to stop Tempe's $2.1 billion deal with the Arizona Coyotes, a move destined to reignite an inter-city conflict over a proposed entertainment district that appeared to have died out four months ago.
The deal involves building a hockey arena, an entertainment district and nearly 2,000 apartments on 46 acres of Tempe-owned land west of Town Lake.
Tempe officials initially greenlighted the project in November, and voters were expected to get the final say during a special election May 16 on whether it moved forward.
Tuesday's lawsuit may throw a wrench into that process.
