Last month we learned from a reported City Hall audit that a wily operator, former Chief Assistant Treasurer Tajel Shah, ignored procurement rules to ensure that a $7 million City Hall contract for a new tax collecting system went to tech corporation Mechanical Orchard. The system handles billions of dollars in San Francisco‘s infamous business taxes. City Attorney David Chiu, City Controller Greg Wagner and the Controller’s Auditor of City Services uncovered Shah’s perfidy. Shah never revealed her friendship with the chief revenue officer of Mechanical Orchard whose subcontractor (Ratio PBC) then hired Ms. Shah’s niece. A complaint was thereafter filed by a knowledgeable citizen with the Ethics Commission in late 2024. The San Francisco Standard reported such malefeasance on Sept. 25, 2025. Mechanical Orchard pulled out of contract talk the day before Shah’s perfidy was revealed. Shah resigned on Nov. 21, 2025.
