Welcome to APRL


Welcome to the Association of Professional Responsibility Lawyers website (“APRL” pronounced April). Originally formed over three decades ago primarily as an association of lawyers who represent other lawyers in disciplinary proceedings, APRL membership now encompasses lawyers who provide services in all aspects of legal ethics and professional responsibility. In addition to respondents’ counsel work, APRL lawyers also represent and advise lawyers and law firms on ethics and professional responsibility, risk management, legal malpractice, and the law of lawyering. APRL also numbers academics and judges among its members. APRL remains the largest organization of lawyers primarily representing other lawyers in disciplinary proceedings. It has over 500 members world wide.

APRL marshals the talent, energy and perspectives of its members to bring about positive change in the areas of legal ethics and the law of lawyering. It also issues public statements and files amicus briefs. APRL and its members are passionate about professional responsibility and together they share their experiences, insights and expertise.

We lost Mark Harrison today.  He will be sorely missed.  He was a pillar of the ethics community for well over 40 years.  He was a founder of APRL, and really of this entire field.  He was one of the very smartest people I have ever met—as well as one of the most articulate.  We argued many times while I was still Bar Counsel.  He literally drove me nuts.  Hey—he drove all of us at the Bar nuts.  But you still had to love the guy.  After I left the Bar, we came to be friends, and he was a good mentor as well.  He never hesitated to help.  Despite the fact that he was always very busy, he was never too busy to take time out to talk about ethics or to brainstorm a problem.

Aside from his many, many professional accomplishments, he was a very kind man.  He was a good friend to many of us.  He was a loving family man.  One of the last things that Mark said to me was this:  “Regrettably, Ellen doesn’t get better but I am happy I’m well enough to tell her every day how much I love her.  We’ve been married almost 63 years!!!”

That was on Christmas day.  Mark said he was feeling great.  He was 85 years old.  Another colleague talked to him last week and he was feeling great then too.  However, on Thursday, he had a small stroke.  He was released from the hospital yesterday.  He passed away today, either of a massive stroke or heart attack – I don’t know which right now.

Given Covid, it is not likely there will be a funeral.  This is devastating because at least then people could gather and remember and honor him.  For those of you that did not really know Mark very well, I am copying and pasting below a blurb from a CLE we did some time back. (See text above “Mark I. Harrison received his LL.B…)

Talk to your friends all that you can, because you never know how long they will be here.



Oh no!

Mark was my good friend for exactly forty years; we met in January 1980 as Bob Kutak was introducing the Commission’s proposed Model Rules of Professional Conduct. I still have my copy of the “puce” bound book of proposed amendments for the final House of Delegates debate at the 1983 Midyear meeting. As it concluded around 10:30 PM, I went around getting signatures of as many of the principal participants as I cold: Geof Hazard, House Chairs Bob Meserve and Stan Chauvin, Mike Franck, Pete Moser, the staff director who for decades made everything ABA  work, Marina Jack, and, of course, Mark who wrote on my book: ‘I’d rather be signing your cast P.S. It was a classy performance.’ I need to bring this precious artifact to a meeting.

Mark was truly a titan; he was also truly a mensch.
