AUBURN HILLS (AP) – The estate of former Detroit Pistons owner Bill Davidson is suing a tax business over a recommended plan lawyers say led to a big Internal Revenue Service claim.

The lawsuit filed Thursday in New York says Deloitte Tax LLP created “a reckless and grossly negligent estate and tax plan,” according to a report in The Detroit News.

Davidson died in 2009 at age 86. He owned Auburn Hills-based Guardian Industries, an auto industry glass products supplier.

The estate in July agreed to pay the IRS $388 million to settle the $2.8 billion claim, which was made in 2013. It says Davidson’s accountants undervalued privately held Guardian stock placed in trusts for his family.
