WilmerHale (full name: Wilmer Cutler Pickering Hale and Dorr LLP) is OUT of the Betancourt, Murphy, and it appears, McBrearty litigation (we don't know yet about the Hayat litigation).

After SO MANY years of representing Wael Al-Mazeedi in all US-based litigation involving partners (Hayat), former investors (IFIC and ASEAN), former employees (Murphy and Betancourt), former contractors (McBrearty) they are gone in the span of a few days!  They've become history.
The following is from Public Access to Court Electronic Records website (US Federal Courts)

Wilmer Cutler Pickering Hale and Dorr LLP: Withdrawing

• Murphy: WH filed Notice of Withdrawal of Appearance (March 31, 2011-April 1, 2011)

Full docket text for document 43:
NOTICE of Withdrawal of Appearance by Joshua D. Jacobson (Jacobson, Joshua)
Full docket text for document 44:
NOTICE of Withdrawal of Appearance by Richard A. Johnston (Johnston, Richard)
Full docket text for document 45:
NOTICE of Withdrawal of Appearance by Harry T. Daniels (Daniels, Harry)

• Betancourt: WH filed a Motion to Withdraw as Attorney (April 4, 2011)

link: Motion for Leave to Withdraw Appearance
link: Affidavit of Richard A. Johnston in Support of Motion for Leave to Withdraw Appearance

Full docket text:
Magistrate Judge Marianne B. Bowler: ELECTRONIC ORDER entered granting [73] Motion to Withdraw as Attorney. Attorney Richard A. Johnston terminated. (Bowler, Marianne)

[Note: WilmerHale got the name of the defendant wrong in their Motion and Affidavit in the Betancourt litigation.  They put in the name of Daniel McBrearty.  This is the reason we are guessing that they are withdrawing from the McBrearty litigation as well.]

 Open-ended Question

They have been Wael Al-Mazeedi's principal cudgel (shock troops, storm troopers, etc.) for ALL kinds of disputes.  Wael Al-Mazeedi could seemingly just simply "beat" people and companies into submission through them.  How (WHY) does someone walk away (if that's what they did) from the source of many thousands (millions?) of US dollars in fees?  I imagine it's not on the basis of higher principles (or maybe IT IS - imagine that, WilmerHale thinking about PRINCIPLES instead of $$$).
