St. John's defence lawyer Averill Baker has been fined by the Law Society of Newfoundland and Labrador, making it the second time the body has sanctioned the lawyer since December.
Baker was disciplined in December for a profanity-laced tirade with a provincial court clerk.
Now, the law society has sanctioned Baker for failing to act with integrity and failing to be honest and candid in advising her client.
The complaint was filed by a client of Baker's in 2011 who was facing a number of criminal and highway traffic act charges.
He said Baker negotiated a plea bargain without his consent, and claimed that because of that plea he involuntarily pleaded guilty to a break and enter charge.
A court appeal later set aside that charge.
A panel at the law society said Baker was sanctioned because she provided misleading information to the law society after her client made the complaint.
Baker was fined $3,500.
