Opinion
Ruby Gross Moore appeals from the denial of her petition, under Government Code section 946.6, 1 for relief from the requirements of section 945.4, which makes presentation of a claim a prerequisite to suit against, in this case, the State of California (the state). The circumstances of this case are unusual if not unprecedented: Ms. Moore filed a timely claim for damages for her injuries but was required to follow the Govern *719 ment Code’s procedures for late claims after the lawsuit based upon her timely, rejected claim was dismissed on the grounds that that claim did not sufficiently embrace the cause of action pled. We have concluded that, given the showing of reasonable mistake below and the state’s failure there even to attempt to demonstrate prejudice, Ms. Moore should have been allowed the relief she sought, and we therefore reverse.
I. Facts and Proceedings Below
The instant proceeding involves Ms. Moore’s efforts to proceed on the merits of a cause of action against the state for negligence in treatment of injuries Ms. Moore suffered while confined at Metropolitan State Hospital. On May 9, 1981, Ms. Moore was assaulted by another patient at that hospital and sustained a fractured jaw. Within 100 days of this occurrence and of attendant treatment for the injury, she filed, through her counsel, a claim with the State Board of Control. 2 The claim alleged substantial injuries and damages resulting from negligence by employees of the state; its full text is set out in the margin. 3
*720 While this claim was under consideration by the Board of Control, Ms. Moore was examined by an oral surgeon at the instance of counsel. On September 14, 1981, the physician reported in writing that Ms. Moore’s serious complaints, including inability to chew any solid foods, misaligned facial appearance, and numbness of the lower jaw, cheeks, and nose, were attributable to insufficient and improper treatment of the May 9, 1981 fracture. (According to Ms. Moore’s account to the physician, her treatment had been limited to little more than an X-ray taken a full week after she was assaulted.) On September 15, 1981, counsel received this report, and this was when he and his client first discovered that medical negligence specifically was implicated. On the same day, the Board of Control summarily denied Ms. Moore’s claim. However, notice of that denial, including the statutorily prescribed warning that suit must be filed within six months (see § 913), was not mailed until December 3, 1981.
Ms. Moore and her counsel proceeded to file a superior court action against the state for “medical negligence.” The complaint was served upon the Attorney General in May of 1982, and the state responded with a demurrer, which was set for hearing on September 7, 1982. The grounds of the demurrer were that Ms. Moore’s timely claim against the state did not sufficiently support or coincide with the cause of action pleaded. (Compare
Nelson
v.
State of California
(1982)
Having thus suffered an adjudication that her previous claim was not a sufficient predicate to the cause of action she sought to assert, Ms. Moore immediately—i.e., on September 10, 1982, three days after the ruling on the demurrer—filed with the Board of Control an application for leave to present a late claim under section 911.4. The board failed to act upon this application within 45 days of its filing, and the application was accordingly deemed denied (§ 911.6, subd. (c)). In the interim, the state’s demurrer to Ms. Moore’s amended complaint was sustained without leave to amend.
Ms. Moore then commenced the present proceeding by filing a petition under section 946.6. This section provides in relevant part that where an application to present a late claim has been denied pursuant to section 911.6 the court shall relieve the claimant of the necessity to file a claim as prerequisite to suit, upon a petition demonstrating the application was made within a reasonable time not in excess of one year from the accrual of the cause of action and “[t]he failure to present the claim was through mistake, inadvertence, surprise or excusable neglect unless the public entity establishes that it would be prejudiced if the court relieves the petitioner . . . .” *721 (§ 946.6, subd. (c)(1).) The petition was supported by exhibits and a declaration of Ms. Moore’s counsel. In opposition, the state filed a brief memorandum of points and authorities which disputed that Ms. Moore’s failure had been “through mistake, etc.” but did not assert that the state would be prejudiced by the granting of relief. The petition was heard by the same judge who had heard and sustained the demurrers to the former pleadings, and was denied.
II. Discussion
As noted above, there are two elements a petitioner must establish under section 946.6. First, he must show that an application for leave to present a late claim was filed within a reasonable time not to exceed one year from accrual of the cause of action upon which suit is sought to be brought. Second, the petitioner must establish one of several alternative excuses for the failure to present a timely claim in the first instance; these include minority or mental or physical incapacitation during all of the time specified by section 911.2 for presentation of the claim (subds. (c)(2), (c)(3)); that the person who sustained the injury or loss sought to be redressed died before expiration of the time for claim presentation (subd. (c)(4)); or, as asserted in the present case, that the failure to present the claim was through mistake, inadvertence, surprise or excusable neglect (subd. (c)(1)). If the petition is grounded upon the latter type of excuse and the petitioner establishes it, the statute provides the further qualification that relief shall be granted unless the public entity establishes that it would be prejudiced thereby. (Id.) We proceed to consider these requisites of section 946.6, subdivision (c)(1) as implicated in the present case.
A. The Failure Timely to File a Second Claim and the Correlative Reliance on the Initial Claim Arose From an Excusable Mistake of Law.
In reviewing the trial court’s denial of the relief provided for by section 946.6, we are both bound and guided by the Supreme Court’s repeated expressions that the statute is to be liberally applied and that particularly close appellate scrutiny should be given to such a denial of relief. The governing rules were most recently restated in
Ebersol
v.
Cowan
(1983)
In applying these rules here, we observe also that the instant case presents particular factual circumstances counseling in favor of allowing Ms. Moore to proceed and against penalizing her by loss of her cause of action. First, Ms. Moore herself is relatively, if indeed not entirely, free of blame: notwithstanding her status as a 63-year-old recent mental patient, she timely retained counsel to pursue her claim and placed the matter in his hands. She thus falls within the class of persons who, “as in previous cases granting relief on the basis of excusable neglect, . . . acted diligently to retain legal counsel within the 100-day limitation period.”
(Ebersol
v.
Cowan, supra,
Quite distinguishable from the foregoing cases or indeed any prior case of which we are aware, the “mistake, inadvertence, surprise or excusable neglect” of counsel at issue in this proceeding involved not failure to invoke the claims procedure at all but rather failure to discern, or to anticipate the trial court’s holding, that a claim actually presented and acted upon by the state was not drafted with sufficient specificity to support or embrace a cause of action for the claimant’s injuries based upon medical negligence. Counsel’s error is thus properly analyzed as a mistake of law, i.e., a mistake occurring “when a person knows the facts as they réally are but has a mistaken belief as to the legal consequences of those facts.”
(Baratti
v.
Baratti
(1952)
Applying these principles as well as the standards of liberality noted above to the peculiar facts of this case, we conclude that counsel’s initial reliance upon the completed claim as the predicate for the medical negligence lawsuit cannot be condemned as unreasonable. Counsel filed a claim on behalf of Ms. Moore which specified that she had suffered “serious, permanent residual damages” flowing from her injury at the state hospital, and in which the nature of the state’s responsibility was broadly couched as arising from negligence by certain employees whose identities were unknown. Notwithstanding this broad recital of the state’s actionable conduct, the state did not respond to the claim with a notice of insufficiency under section 910.8. 4 This inaction bolstered the viability of the claim by reason of section 911, which provides in relevant part that “[a]ny defense as to the sufficiency of the claim based upon a defect or omission in the claim as presented is waived by failure to give notice of insufficiency with respect to such defect or omission as provided in section 910.8 . . . .” Thereafter the state issued a flat rejection of the claim, with the standard notice that any suit based upon the claim had to be brought within six months (see § 913). Taken together, these circumstances could properly inspire a reasonable apprehension that the claims-presentation process had been satisfied and that the time was ripe for commencement of an action to litigate responsibility for the state’s negligence, including the medical negligence charged in the complaint that soon was filed.
The state contends, however, that counsel’s decision so to proceed— rather than, presumably, filing an amended or a second complaint—should be deemed inexcusable under that principle that “[i]gnorance of the law, at least where coupled with negligence in failing to look it up, . . . will certainly sustain a finding denying relief.”

City of Monterey
(1953)
The foregoing analysis is not, of course, meant to essay or establish that the trial court erred in sustaining the demurrer to Ms. Moore’s complaint on the ground that it was insufficiently embraced within the claim her counsel filed. It does however demonstrate that the sufficiency of that claim and complaint involved a debatable issue, and hence counsel’s mistake of law in relying upon the original claim rather than filing another was reasonable
*725
and excusable. (See
City of Ontario
v.
Superior Court
(1970)
B. Ms. Moore’s Application for Leave to File a Late Claim Was Clearly Made Within a “Reasonable Time” as Required by Section 946.6, Subdivision (c).
Having determined that the failure timely to file an amended or a second claim elaborating upon the cause of action for medical negligence was the result of an excusable mistake of law as to the adequacy of the claim that had been acted upon, we have no difficulty in concluding that Ms. Moore’s application for leave to present the further claim as a late claim “was made within a reasonable time not to exceed that specified in subdivision (b) of Section 911.4,” as required by section 946.6, subdivision (c). The period so specified by section 911.4, subdivision (b) is one year after accrual of the cause of action. Here, the state concedes that, in light of the rule that a cause of action for medical negligence accrues upon discovery of the injury and its negligent cause
(Whitfield
v.
Roth
(1974)
Nonetheless, the state contends that this period of nearly one year must be deemed unreasonable as a matter of law. To the contrary, counsel’s and Ms. Moore’s action of September 10, 1982, was reasonable as a matter of law, for it occurred only three days after the state’s initial demurrer to the
*726
complaint had been sustained on the grounds that the claim was insufficient to support it. Only then was Ms. Moore’s honestly held and earnestly argued legal position determined actually to have been mistaken, and until then there implicitly was no basis for Ms. Moore or her counsel to seek to file a further claim. “Where, as here, plaintiff’s mistake was the actual cause of his failure to comply ... his application to the board could obviously not have been made until he discovered his mistake, and the delay was, therefore, reasonable under the circumstances.”
(Viles
v.
State of California, supra,
C. The State’s Failure to Present Any Allegation or Proof of Prejudice Requires That Plaintiff Be Granted Relief
We have determined above that Ms. Moore’s late-claim application was filed within a reasonable time not exceeding one year from the accrual of her cause of action, and that failure to file a second or amended claim within the normal time limits was the result of an excusable mistake. Section 946.6, subdivision (c)(1) provides that in these circumstances the court “shall” grant relief “unless the public entity establishes that it would be prejudiced” by such action. In the proceedings below the state offered no evidence or argument whatsoever that it would be so prejudiced. Absent any such allegation or offer of proof of impending prejudice, Ms. Moore’s petition must be granted, under the very terms of the statute.
(Syzemore
v.
County of Sacramento
(1976)
In opposition to this conclusion, the state relies upon a number of decisions, affirming denials of relief under section 946.6, which recite that the public entity in question had no burden of proving prejudice “until [the claimant] satisfied the trial court that [his or her] failure to file a timely claim was due to mistake, inadvertence, surprise or excusable neglect.”
(Shank
v.
County of Los Angeles
(1983)
It is true that in order to prevail in a proceeding under section 946.6, subdivision (c)(1) the public entity need not carry its burden of proof of prejudice unless and until the plaintiff’s burden of showing the initial preconditions of reasonable timeliness and mistake, etc. has been met. But this does not mean that a public entity that offers no claim or evidence of prejudice before or at the time of the hearing on the petition should automatically be allowed a “second shot” on the issue of prejudice (actually a first one) upon reversal of a determination adverse to the plaintiff. If this were allowed, the result would be repeated, piecemeal litigation of petitions designed to expedite proceedings for the benefit of both parties, and, in some cases, successive, fragmentary appeals from repeated adverse decisions by trial courts. This prospect is inconsonant with both the policies of section 946.6 and the statute’s provision for a unitary determination of the issues. (See § 946, subd. (e) (“The court shall make an independent determination upon the petition. The determination shall be made upon the basis of the petition, any affidavits in support of or in opposition to the petition, and any additional evidence received at the hearing on the petition.”).) The cases cited by the state cannot reasonably be read to prescribe or authorize such a convoluted procedure where the public entity has made no effort to estab-. lish prejudice in the first instance. 6
We conclude, therefore, that since Ms. Moore’s petition was sufficient to satisfy the preconditions for relief under section 946.6 and the state made no effort whatsoever to assert or establish prejudice below, Ms. Moore is now entitled to relief under the terms of section 946.6, subdivision (c)(1).

The order appealed from is reversed and the matter is remanded with directions to enter an order granting appellant’s petition.
Thompson, Acting P. J., and Beverly, J., * concurred.
A petition for a rehearing was denied July 12, 1984, and respondent’s petition for a hearing by the Supreme Court was denied August 22, 1984.
