TOPEKA, Kan. (AP) — Kansas legislators have ended their regular session and started a three-week break with several major issues unresolved.

The House and Senate adjourned Friday evening. Lawmakers will return to Topeka on April 25 to wrap up the year's business, although some committees will return early to discuss remaining pieces of legislation.

Among the key issues will be settling differences on a proposed $14 billion budget for the fiscal year that starts July 1. Negotiators were close to agreement Friday, but talks broke down over technical issues.

The issue was how to cover $25 million in unexpected costs faced by the state's 286 school districts. The House had proposed diverting money from highway projects, an idea not in Gov. Sam Brownback's budget recommendations or approved by the Senate.

The failure of Kansas lawmakers to approve a state budget could also mean furloughs in the court system.

Chief Justice Lawton Nuss told lawmakers in February the judicial branch was facing a $1.4 million shortfall in the current budget year. Nuss requested a supplemental appropriation to prevent five-day furloughs of about 1,500 court employees.

It's unclear whether the furloughs can be avoided if legislators approve the funding request after they return to work April 25.

Legislators also must finish redrawing the 40 state Senate, 125 state House and four U.S. House districts to reflect population changes as recorded by the 2010 census.

Tax cuts — a key part of Gov. Sam Brownback's agenda — also remain on the table.
