MEMORANDUM **

Jason Saunders, a California state prisoner, appeals pro se from the district court’s judgment dismissing his 42 U.S.C. § 1983 action for failure to pay a filing fee, after it denied Saunders in forma pauperis status on the ground that Saunders had “three strikes” under 28 U.S.C. § 1915(g). We review de novo a district court’s application of § 1915(g), Andrews v. King, 398 F.3d 1113, 1118 (9th Cir. 2005), and we vacate and remand.

The district court improperly denied Saunders’ request to proceed in forma pauperis because Saunders’ proposed amended complaint made plausible allegations that he was “under imminent danger of serious physical injury” at the time he lodged the complaint. 28 U.S.C. § 1915(g); see also Andrews v. Cervantes, 493 F.3d 1047, 1055 (9th Cir. 2007) (an exception to the three-strikes rule applies “if the complaint makes a plausible allegation that the prisoner faced ‘imminent danger of serious physical injury’ at the time of filing”). Moreover, the district court erred in denying Saunders leave to file his proposed amended complaint because it was the first amended complaint in case number l:06-cv-01567 and Saunders was entitled to amend his complaint once as a matter of right prior to a responsive pleading being filed. See Fed.R.Civ.P. 15(a)(1); Jones v. Bock, 549 U.S. 199, 214, 127 S.Ct. 910, 166 L.Ed.2d 798 (2007) (“PLRA’s screening requirement does not — explicitly or implicitly — justify deviating from the usual procedural practice beyond the departures specified by the PLRA itself.”).

Saunders’ motion to stay the briefing in this appeal, submitted on December 10, 2012, is denied as moot.

VACATED and REMANDED.
