Those involved in it, in publicizing it through media, in testifying in court about it in an official capacity, etc, are subject to public scrutiny.

As for my changing lawyers four times, the Society's Superior General originally entrusted my defence to the Society's lawyer, Maximilian Krah, who chose to engage Matthias Lossmann, a member of the, alas, anti-Catholic Green Party. He was conscientious but perhaps not too enthusiastic about the case. Through friends, I discovered a lawyer enthusiastic and highly successful in defending such delicate cases, Wolfram Nahrath, but Lossmann was unwilling to work with him. Seeking only the best legal counsel available to me in my quandary, I switched from Lossmann to Nahrath.

It is absolutely scandalous that someone with pro-Zionist sympathies should hire someone from the leftist Green party to represent Bishop Williamson, someone in trouble with the Zionist lobby.

Very clearly, this is a public matter of grave importance.

from another forum:

1—12-13 January 2010
 The first event is his attempt to force Bishop Williamson to give an interview to the German leftist magazine, Der Spiegel, by forcing their way inside St Georges House on the 12 and 13 January 2010.
The Bishop had already refused to receive the SSPX lawyer K and the two Spiegel journalists even before arriving in London – in other words, they were aware while still in Germany that Bishop Williamson had no intention of giving them an interview:
This is confirmed in the article written by Stephen Heiner who had visited the Bishop straight after:

“K insists on coming for the pre-interview “coaching session.” The Bishop expresses the discomfort he has with K’s proposal and expresses the desire to change the interview format to the same as last time: written questions. Such a situation would make any London visit of K and the journalists unnecessary. The Bishop says to K, “Do NOT come, because I will not speak”.”

A totally distorted and anti-clerical article appears in the Spiegel shorly after the event.

2 – 4 July 2011
The second event is the strange behaviour displayed by the German SSPX lawyer K during the trial of Bishop Williamson in Regensburg (4 July 2011), where he was supposed to be a witness for the defence on 4 July 2011. He acted more like the prosecutor rather than a witness for the defence.

The lawyer ridiculed the Bishop in describing him as “colourful bird”, who has “no significant position of leadership”, an “eccentric”, “one who had a persistent problem with recognition of reality" and "monotonous regularity every two years, believes in the apocalypse."

What Bishop Fellay did is to have someone with the sympathies of Alan Dershowitz simultaneously manage the bishop's defense while this same person was engaged in a world press campaign against the Bishop.

I would think such behavior should cause a person to lose their right to practice law.
