ChatGPT: 被法院净block的行政命令，Trump第一任期有41个，拜登有7个

Focusing on nationwide injunctions (the best-measured category):

President / Period	Nationwide injunctions blocking admin policies (approx.)	Cases with meaningful appellate reversal (merits or nationwide scope)
Trump – 1st term (2017–2021)	64 Congress.gov+1	≈23 cases (17 reversed on merits + 6 reversed as nationwide injunction) Congress.gov
Biden – through Mar 2025	14 in first 3 years; ≈28 cases total in CRS dataset by 3/2025 Congress.gov+2Congress.gov+2	≈7 cases (3 reversed on merits + 4 reversed as nationwide) Congress.gov

These numbers answer your question as well as the current empirical work allows, but they’re necessarily approximate and limited to nationwide injunctions, not every single judicial check on an executive order.
