This malpractice case presents the problem of proper application of the provisions of sections 379a and 379e of the Code of Civil Procedure, added to the code in 1927, relating to joinder of parties defendant, in the light of the provisions of section 427 of the same code, relating to joinder of causes of action. The latter section was enacted in 1872 and, except as hereinafter mentioned, has not been amended since 1915.
Plaintiffs, husband and wife, have joined as defendants in one action Drs. Joseph Smith and E. C. Innis, physicians and surgeons, who, independently of each other, treated plaintiff wife at different times and places, but the treatment of each of whom, it is alleged, contributed to aggravating certain injuries she had previously received. Dr. Innis filed a general and special demurrer to the second amended complaint, specifying as grounds of special demurrer that there was a misjoinder of parties defendant and of causes of action and that uncertainties appeared in various particulars. From a judgment entered on an order sustaining the demurrer without leave to amend, plaintiffs appeal.
In count one of their pleading plaintiffs allege that on June 15, 1940, defendant Smith, practicing in Bakersfield, California, was employed to treat certain injuries which immediately theretofore had been sustained by plaintiff Wanda Kraft, including a broken ankle, a broken leg, and a fractured knee; that she received negligent and improper treatment from such defendant and thereby suffered further injury.
The allegations of count two are not here in issue and need not be discussed.
In count three it is alleged that on June 24, 1940, plaintiffs employed defendant Innis, practicing in Newhall, California (approximately 65 miles from Bakersfield and in a different county), to treat the same injuries of plaintiff wife which had been treated by defendant Smith; that she received negligent and improper treatment from defendant Innis and was damaged thereby to such an extent that, among other consequences, her right leg was made permanently shorter than her left leg; and “that the plaintiffs are in doubt as to whether they are entitled to redress from the defendant Joseph Smith or the defendant Innis, or both of them, for the resultant injuries, in that these plaintiffs are unable to presently ascertain whether or not the final result of the *127 negligence herein alleged was caused by the negligence in the treatment by defendant Joseph Smith, or the negligence in the treatment by the defendant B. C. Innis, or the negligence of both of them and for that reason both defendants have been joined herein with the intent that the question as to whether both of said defendants are, or one of them is, liable to the plaintiffs and to what extent, and that said liability may be determined in this action and that the Court may award judgment to the plaintiffs as against the defendants either jointly, severally, or in the alternative.”
Count four incorporates all of the allegations of the first and third counts, and in addition alleges that “as a direct and proximate result of the negligence and carelessness of the defendants, and each of them, plaintiff Boy Kraft has been forced to incur certain medical expenses and will be forced to incur additional medical expenses in an amount not now ascertainable, and plaintiff will ask leave to insert the amount when the same is ascertained.”
Bespondent (defendant Innis) contends that inasmuch as joint negligence between him and defendant Smith is not alleged and the tort of which each is accused is separate and independent, the causes of action based on such separate torts may not properly be joined in one action. We have concluded, however, that by virtue of the provisions of sections 379a and 379c of the Code of Civil Procedure joinder is now permitted under the circumstances here alleged. Those sections read as follows:
Section 379a: “All persons may be joined as defendants against whom the right to any relief is alleged to exist, whether jointly, severally or in the alternative; and judgments may be given against such one or more of the defendants as may be found to be liable, according to their respective liabilities. ’ ’
Section 379c: "“Where the plaintiff is in doubt as to the person from whom he is entitled to redress, he may join two or more defendants, with the intent that the question as to which, if any, of the defendants is liable, and to what extent, may be determined between the parties.”
Bespondent argues that the requirement of section 427 of the Code of Civil Procedure that the causes of action which it provides may be united “must affect all the parties to the action” controls over the more liberal and more recently enacted sections 379a and 379c. A similar contention

Peters
v.
Bigelow
(1934),
We are satisfied that the same view, applied to the instant case, is determinative of the problems here presented, and that the joinder invoked by plaintiffs falls squarely within the provisions of sections 379a and 379c. The doubt which plaintiffs allege “as to the person from whom . . . [they are] entitled to redress” (sec. 379c), thus necessitating that relief be sought from the two defendants either “jointly, severally or in the alternative” (sec. 379a) can well be under

stood under the circumstances, and to require that separate actions be brought, in both of which actually, as a practical matter, both defendants would be substantially interested, would be to impose inefficient procedure and unnecessary waste of time and money upon all parties concerned and the state itself. It would appear that one of the chief purposes of the new sections—379a, 379b and 379c—is to avoid just such multiplicity of actions. As early as 1891 this court intimated the need for some such legislation in furtherance of justice. In
Miller
v.
Highland Ditch Co.
(1891),
Although the complaint before us is far from being a model of clarity, conciseness, or consistency, it does fairly appear therefrom that plaintiff Wanda Kraft sustained certain severe physical injuries, that the defendants were severally and successively employed to treat such injuries, that each defendant was negligent in the treatment he administered, and that as a proximate result of the negligence of one or the other or both of the defendants the plaintiff Wanda Kraft sustained further injury, i. e., a condition necessitating the
*130
rebreaking of one or both of her legs, the permanent shortening of one leg, etc. Certainly neither defendant is liable for any injury caused by the independent tort of his co-defendant, to which he himself did not proximately contribute. If upon the trial it develops that neither defendant was guilty of negligence then no prejudice will have been occasioned by their joinder in the one action. If it develops that only one defendant was negligent in his treatment the assessment of the verdict will be simple. If, on the other hand, it appears that negligence of both, defendants contributed proximately to cause an injury for which plaintiff is entitled to recover, it may be a matter entailing great difficulty of proof as to the amount in which each defendant is responsible. (Cf.
Slater
v.
Pacific American Oil Co.
(1931),
The facts that defendants are not joint tort feasors but independent wrongdoers, and that their negligence operated successively rather than concurrently in time to produce the injury, are not vetitive of the right of joinder. The salutary procedure afforded by sections 379a, 379b and 379e of the Code of Civil Procedure is clearly intended to be available upon a showing either that the negligence of two or more persons, whether joint, independently concurrent, or successive, contributed proximately to cause the injury for which recovery is sought, or that the injury for which recovery is sought was proximately caused by the negligence of one or another or several of two or more persons and, as to each person who is not charged absolutely, that a reasonable *131 uncertainty, requiring determination of some factual or legal issue, exists in respect to alternative or quantitative liability.

In the Mordecai case (1933),
supra,
Returning to the pleading in the case before us, count three states a cause of action against defendant-respondent Innis and is not improperly joined with count one which states a cause of action against defendant Smith. The fact that some or all of the specified uncertainties in the several counts were justifiably urged as grounds for special demurrer and properly required an order sustaining the demurrer, cannot be availed of to support the judgment, which is based on the order sustaining the demurrer
without leave to amend.
The denial of permission to amend was probably based on the view that Drs. Innis and Smith could not, under the circumstances pleaded, be joined as parties defendant in the same action. That position, as we have shown, is not sustainable. Hence the judgment must be reversed because it would be an abuse of discretion not to grant plaintiffs leave to amend for the purpose of removing mere uncertainties in the phraseology of expression of their causes of action. (See

v.
Hollywood Hospital
(1941),
The judgment is reversed with directions to the trial court to grant the plaintiffs a reasonable time within which to prepare, serve, and file a further complaint, amended in such particulars as plaintiffs may be advised.
