When #Congress objects to a #DC #law, disapproval resolutions have the effect of rendering it null & void. But Schwalb (D) argues in his opinion that Congress missed a critical 30-day deadline & also failed to make the resolution apply retroactively, given the 2025 #tax season already began. As a result, Schwalb says, the disapproval has no effect on the city’s tax laws, & DC tax filers should proceed without any disruption or change to the rules.
