Delaware Court of Chancery Issues Important Ruling for Multi-Class Companies Addressing Class Votes
Earlier today, Vice Chancellor J. Travis Laster of the Delaware Court of Chancery issued an important ruling concluding that two companies with multiple classes of common stock were not required, under the Delaware statute, to obtain separate class votes of their stockholders in order to amend their certificates of incorporation to provide for exculpation of their officers.1 Those charter amendments took advantage of the recent amendments to the Delaware General Corporation Law (the DGCL) permitting Delaware corporations to provide in their certificates of incorporation that, akin to protections long afforded to directors, specified officers of the corporation can be protected from monetary liability for certain breaches of fiduciary duty—specifically, direct, though not derivative, claims by stockholders asserting a breach of the duty of care. Today’s ruling, pending any appeal, is good news for dual-class companies seeking to amend their charters to implement officer exculpation and will also have broader implications for private and public companies assessing whether to seek a class or series vote of stockholders for other charter amendments. Wilson Sonsini is representing one of the defendant companies in the case.

Pro Bono Team Secures Deferral of Removal for Client from Nigeria
On October 3, 2022, a Wilson Sonsini pro bono team led by Of Counsel Ariel Anaba secured deferral of removal for Jon (not his real name), a Nigerian immigrant who had served a substantial federal sentence and was set to be deported from the United States. Jon is bisexual, and in light of Nigeria’s hostility toward LGBTQ+ individuals, a decision sending him back to his native country would have been catastrophic.
Ariel, along with partner Mark Yohalem, initially took on the representation of Jon in 2017, before joining Wilson Sonsini. Over the next five years, she succeeded first in the Ninth Circuit, then in the Board of Immigration Appeals (BIA), and then before the Immigration Judge (IJ). After convincing the Ninth Circuit and BIA to reopen the case, the core challenge was to convince the IJ that Jon was bisexual, notwithstanding his having spent his life in the closet (such that he essentially had no corroborative evidence) and his having been convicted of fraud. Ariel’s written work and oral advocacy presented the story of Jon’s life in a way that rang with truth, and in the case’s final stage, Callie Davidson became involved to conduct Jon’s direct examination, which went extremely well.
As a result of the October 3 victory, Jon will not be sent back to be tortured and killed in Nigeria.
In addition to Ariel, Mark, and Callie, the Wilson Sonsini pro bono team that assisted Jon in the matter included John Roberts, Katie Obermiller, Kristijonas Rastauskas, Diana Lopez, and Tatiana Thomas.
