On March 27, 2026, Sacramento Superior Court Judge Stephen Acquisto denied the California Department of Water Resources' motion to disqualify Somach Simmons & Dunn, the law firm that has represented the County of Sacramento, City of Stockton, and other local agencies in Delta Conveyance litigation since 2007. DWR's motion, supported by some 5,000 pages of filings, argued that attorney Casey Shorrock's prior work on a 2020 Initial Study/Mitigated Negative Declaration (IS/MND) for geotechnical investigations created a disqualifying conflict of interest.

Dr. Hussam Abu Safiya, who has been in Israeli detention since December 2024, is in a "dire" health condition, United Nations experts warned as they called for his immediate release.

Part 2: The leading mode of North American winter circulation has changed, and March 2026 is what the new mode produces In Part 1, I described the diabatic engine behind March 2026's record-shattering western heat dome: upstream precipitation in the Pacific Northwest released latent heat that amplified an extraordinary ridge over the interior West. That post explained the mechanism. This one asks a different question: why does the ridges keep forming?

And why the same mechanism that built the 2021 Pacific Northwest heat dome is doing it again, in early spring As I write this in mid-March 2026, the western United States is in the grip of a heat wave that has no precedent in the cool-season observational record. Downtown Los Angeles hit 92°F last Thursday. Phoenix is on track for its earliest 100°F day ever, beating the previous record by more than a week.

The week of February 23-27 presents attorneys representing Delta communities with an impossible calendar. The State Water Board's Delta Conveyance Project water rights hearing has added February 23, 24, and 25 as hearing days. The Delta Stewardship Council has scheduled its appeal hearing on DWR's certification of consistency with the Delta Plan for February 26 and 27—and has required that parties appear in person.

On Monday, February 9, 2026, Administrative Hearing Officer Nicole Kuenzi denied Somach Simmons & Dunn's motion to stay the Delta Conveyance Project water rights hearing pending resolution of DWR's disqualification motion in Sacramento Superior Court. The hearing will continue as scheduled, with most of the protestants' rebuttal case likely to conclude before the March 20 court hearing on DWR's motion.

Sacramento County Superior Court Judge Stephen Acquisto today granted Somach Simmons & Dunn’s motion to stay the consolidated Delta Conveyance Project CEQA cases through March 27, 2026. He set a hearing on DWR’s motion to disqualify the firm as counsel for Sacramento County and the City of Stockton for March 20, 2026. From the bench, the judge described the potential disqualification as “monumental.” He indicated that he understood how severely it would impact Somach’s clients: local governments representing approximately two million Delta-area residents who have relied on the firm’s representation in Delta Conveyance matters since 2007.
