Salem Trust Co. v. Manufacturers’ Finance Co., 264 U. S. 182, 189, 190; Saint Paul Mercury Indemnity Co. v. Red Cab Co., 303 U. S. 283, 294, 295.
The question then is whether the original complaint set forth a separable controversy between the plaintiffs and the Pullman Company, that is, a controversy “which is wholly between citizens of different States, and which can be fully determined as between them.” 28 U. S. C. 71. If, as to the non-resident defendant seeking removal, the controversy is separable within the purview of the statute as construed, the fact that under the state practice it may be joined in the same suit with another controversy as against other defendants, does not preclude removal. Barney v. Latham, supra; Nichols v. Chesapeake & Ohio Ry. Co., 195 F. 913, 915, 916; Stewart v. Nebraska Tire & Rubber Co., 39 F. 2d 309, 311; Des Moines Elevator Co. v. Underwriters’ Grain Assn., 63 F. 2d 103, 105; Culp v. Baldwin, 87 F. 2d 679, 680-682.
This is so whether the action sounds in contract or in tort. The question is determined by the plaintiff’s pleading. Thus if defendants are charged with negligence, but the charge against the non-resident defendant' is based on different and non-concurrent acts of negligence and a cause of action which is joint in character is not alleged, a separable controversy is presented. See Culp v. Baldwin, supra. Where, in the absence of clear proof of bad faith in the joinder, concurrent acts of negligence on the part of the defendants sued as joint tort-feasors are sufficiently alleged, a separable controversy is not presented and the fact that the defendants might have been sued separately affords no ground for removal. This rule is applied where a non-resident employer and its resident employee, whose negligence caused the injury, are sued jointly. Chesapeake & Ohio Ry. Co. v. Dixon, 179 U. S. 131, 139; Alabama Great Southern Ry. Co. v. Thompson, 200 U. S.
