An Easton city solicitor is investigating whether the city’s new charter prohibits Pam Panto from serving on City Council, and a legal opinion could be issued as early as today.

On Jan. 2, City Council appointed Panto, whose four-year term on council had just ended, to fill the vacancy.

The inquiry stems from a 42-word provision in the new charter involving former council members, city officials said.

‘‘No former council member shall hold any compensated appointive city office or city employment … until one year after the expiration of the term,’‘ the provision states.

Panto called the review ‘‘ridiculous,’‘ saying ‘‘it’s just another attempt to get me off City Council.’‘
