Esther Cunningham drank brandy before appearing as a solicitor to represent her cousin in a dangerous dog case.
She told an usher to ‘f*** off’ and called the CPS lawyer ‘a f***wit’, the Solicitors’ Disciplinary Tribunal heard.
Six months later, the 54-year-old was drunk when she taught students on a legal course, the tribunal heard.
Cunningham, of Grantham, Lincolnshire, accepted she had a drink problem and blamed it on personal problems.
She admitted bringing her profession into disrepute two years ago and was suspended for six months with £6,200 costs.
