NEW YORK (AP) - Lawyers warned five years ago that New Jersey Gov. Chris Christie's decision to take $1.8 billion from a bistate agency to fix state roads might cause legal problems.

NEW YORK (AP) Lawyers warned five years ago that New Jersey Gov. Chris Christie's decision to take $1.8 billion from a bistate agency to fix state roads might cause legal problems.

They turned out to be right.

The Port Authority of New York and New Jersey's expenditure on the Pulaski Skyway repairs has become a central part of a lawsuit filed by AAA against the agency over 2011 toll hikes.

On Thursday, lawyers for both sides will argue before a federal judge in New York.

But the Port Authority's spending on Pulaski repairs is also being challenged by an airline, probed by the Federal Aviation Administration and investigated by both the Securities Exchange Commission and the Manhattan district attorney.

The Port Authority has argued the expenditure was proper regardless of whether AAA agrees.
