In the first day of the trial in a lawsuit to stop the renovation of a historic stadium in Franklin Park, attorneys for the plaintiffs argued Tuesday that the changes to the park would be so substantial that they required approval by the state Legislature.

With the help of a new professional women's soccer team, Boston is set on remaking White Stadium in Franklin Park. Local advocates say the city is breaking state law.

After the plaintiffs’ final witness, the judge denied a request from the defendants to issue a ruling that the plaintiffs had not made a case for an Article 97 violation.
