INDIANAPOLIS (AP) — IBM Corp. owes Indiana $78 million in damages stemming from the company's failed effort to automate much of the state's welfare services, a judge has ruled in a long-running dispute.

Marion Superior Court Judge Heather Welch issued the ruling dated Friday, nearly six months after she heard arguments from attorneys for the state and IBM. The Indiana Supreme Court ruled last year that IBM had breached its contract and it directed the trial court to calculate the damages.

Indiana and New York-based IBM sued each other in 2010 after then-Gov. Mitch Daniels cancelled the company's $1.3 billion contract to privatize and automate the processing of Indiana's welfare applications.

Under the deal, an IBM-led team of vendors worked to process applications for food stamps, Medicaid and other benefits. Residents could apply for the benefits through call centers, the internet and fax machines. The contact was pulled in late 2009, less than three years into the 10-year deal, following complaints about long wait times, lost documents and improper rejections.

The state sought more than $172 million from IBM, but the judge ruled IBM responsible for $128 million in damages. That amount was offset by about $50 million in state fees that the company was owed.

Peter Rusthoven, one of the state's private attorneys, said Monday that the ruling would be carefully reviewed before deciding on any additional appeals.

"Overall, we are extremely gratified by the result and thinks it really vindicates the position the state took throughout this really long battle," Rusthoven said.

IBM and its attorneys didn't immediately reply to Monday phone messages seeking comment.

The state argued that IBM owed Indiana for the cost of fixing the company's problematic automation efforts to make the system workable, paying overtime for state staffers to review and correct those problems, and hiring new staff to help oversee that process, among other expenses.

IBM's attorneys argued that the company had delivered "substantial benefits" to the state that undermined Indiana's damages claims.

Welch heard arguments from both sides on Feb. 10. She was scheduled to rule by early May in the complicated case, but lawyers twice agreed to allow the court more time.
