TOPEKA, Kan. (AP) — The $12.2 billion sale of Topeka-based Westar Energy to Great Plains Energy has cleared legal challenges after parties in lawsuits challenging the deal have agreed to drop the cases.

Missouri-based Great Plains is the parent company of Kansas City Power & Light.

The Topeka Capital-Journal reports that new Securities and Exchange Commission filings show the three complaints will be dropped. Two were in Kansas and one was in Missouri.

One of the Kansas complaints filed in July alleged members of Westar’s energy board of directors failed to obtain the best price for shareholders because of a process that discouraged third parties from submitting potentially better proposals.

The sale still faces a review by several agencies, including the Kansas Corporation Commission, the Federal Energy Regulatory Commission and the Nuclear Regulatory Agency.
