Testwell Inc. asserts in state Supreme Court papers that the city suspended its licenses "unlawfully" in October after the company was indicted on enterprise corruption charges. Testwell says the charges have not been proven.

Testwell says an administrative law judge recommended lifting the suspensions but last week the city rejected that recommendation.

The city Law Department says it is reviewing Testwell's court papers. The city has been attempting to retest concrete and steel handled by Testwell on some buildings, although prosecutors say no weaknesses have been found.
