CIVIL MINUTES - GENERAL
MARGARET M. MORROW, District Judge.
Proceedings: Order Remanding Case to Los Angeles Superior Court for Lack of Subject Matter Jurisdiction
I. FACTUAL BACKGROUND
Plaintiff Investment Management Company, LLC filed this unlawful detainer action in Los Angeles Superior Court against Svetlana Cholakian ("Cholakian") and certain fictitious defendants on December 18, 2012. Defendants are allegedly holdover occupants in possession of real property located in Tarzana, California ("the property"). Plaintiff acquired ownership of and title to the property at a duly noticed trustee sale, and it has allegedly perfected its title pursuant to California Civil Code §§ 2924 et seq. 
On or about November 17, 2012, plaintiff served a written notice to quit and deliver up possession of the property on defendants pursuant to California Code of Civil Procedure § 1162. It alleges that defendants have failed to vacate or deliver possession of the property.
Plaintiff seeks restitution of the property, holdover damages of $70.00 per day from November 21, 2012 until the date judgment is entered, and its costs of suit.
Cholakian filed a notice of removal on April 4, 2013, invoking the court's federal question jurisdiction.
A. Legal Standard Regarding Removal Jurisdiction
Federal courts have a duty to examine their subject matter jurisdiction whether or not the parties raise the issue. See United Investors Life Ins. Co. v. Waddell & Reed, Inc., 360 F.3d 960, 966 (9th Cir. 2004) ("[A] district court's duty to establish subject matter jurisdiction is not contingent upon the parties' arguments, " citing Mitchell v. Maurer, 293 U.S. 237, 244 (1934)); see also Attorneys Trust v. Videotape Computer Products, Inc., 93 F.3d 593, 594-95 (9th Cir. 1996) (lack of subject matter jurisdiction may be raised at any time by either party or by the court sua sponte ); Thiara v. Kiernan, No. C06-03503 MJJ, 2006 WL 3065568, *2 (N.D. Cal. Oct. 25, 2006) ("A district court has an independent obligation to examine whether removal jurisdiction exists before deciding any issue on the merits").
Where a case has been removed, the court may remand for lack of subject matter jurisdiction at any time before final judgment. See 28 U.S.C. § 1447(c) ("If at any time before final judgment it appears that the district court lacks subject matter jurisdiction, the case shall be remanded"). The court may - indeed must - remand an action sua sponte if it determines that it lacks subject matter jurisdiction. See Kelton Arms Condominium Owners Ass'n v. Homestead Ins. Co., 346 F.3d 1190, 1192 (9th Cir. 2003) ("[W]e have held that the district court must remand if it lacks jurisdiction, " citing Sparta Surgical Corp. v. Nat'l Ass'n Sec. Dealers, Inc., 159 F.3d 1209, 1211 (9th Cir. 1998)). For the reasons discussed below, the court lacks subject matter jurisdiction and the action must be remanded to Los Angeles Superior Court.
B. Federal Question Jurisdiction
1. Legal Standard Governing Federal Question Jurisdiction
Under 28 U.S.C. § 1331, district courts "have original jurisdiction of all civil actions arising under the Constitution, laws, or treaties of the United States." Federal question jurisdiction is presumed absent unless defendant, as the party seeking to invoke the court's jurisdiction, shows that plaintiff has either alleged a federal cause of action, American Well Works Co. v. Layne & Bowler Co., 241 U.S. 257, 260 (1916) ("a suit arises under the law that creates the action"), a state cause of action that turns on a substantial dispositive issue of federal law, Franchise Tax Bd. v. Construction Laborers Vacation Trust, 463 U.S. 1, 9 (1983); Smith v. Kansas City Title & Trust Co., 255 U.S. 180, 199 (1921), or a state cause of action that Congress has transformed into an inherently ...
