Basis of termination
From the record · verbatim“On April 22, 2026, Plaintiff dismissed all claims in this case with prejudice. (Dkt. 7). Rule 41(a)(1)(A)(i) allows a plaintiff to voluntarily dismiss an action without a court order by filing a notice of dismissal before the opposing party serves an answer or a motion for summary judgment. Fed. R. Civ. P. 41(a)(1)(A)(i). Defendant has not served an answer or motion for summary judgment. Plaintiff’s notice is therefore “self-effectuating and terminates the case in and of itself; no order or other action of the district court is required.” In re Amerijet Int’l, Inc., 785 F.3d 967, 973 (5th Cir. 2015), as revised (May 15, 2015).”
