How Judge Wang decides
Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.
What persuades
For interior noncitizens detained without an individualized bond hearing, Wang applies the bond-hearing statute and orders a prompt hearing with the government bearing the clear-and-convincing burden or release.
“As this Court has previously explained, Santillan Quiroz ‘controls’ a case where, as here, a noncitizen residing in the interior of the United States is detained without a bond hearing.”
Procedural preferences
In one expert-testimony dispute, Wang excluded a purported rebuttal opinion that ventured into a legal determination or an assessment of another expert’s permissible scope.
“The Court agrees that this ‘opinion’ is not admissible. Although the meaning behind Dr. Shelby’s statement is not entirely clear, this statement is either an improper legal determination, not proper rebuttal testimony, or outside of the scope of Dr. Shelby’s expertise.”

The table leaves out prisoner petitions, land condemnations, deportation reviews, recovery of overpayments and enforcement of judgments, and reports no median for fewer than 10 cases. A district that closed a large multidistrict litigation in the period shows very large counts and long medians for that year. Source: Table C-5, U.S. District Courts (spreadsheet).
