the sierra club and aclu brought a similar suit. in 2019, a u.s. district court issued a preliminary injunction, and later a permanent injunction, in the sierra club suit, blocking trump from diverting military funds for construction of a border wall. in july 2019, the supreme court, in a 5–4, one-paragraph ruling, overturned the lower court's ruling in "trump v. sierra club" that blocked the use of funds to construct the border wall pending further legal proceedings; the supreme court majority found that the sierra club likely lacked legal standing.
