416 N.E.2d 516
Mass. App. Ct.
1981
Kass, J.

A wolf in the New Bedford Buttonwood Park Zoo, a city facility, pushed enough of his snout through his pen to bite the plaintiff’s finger. This action against the superintendent of parks of New Bedford alleged negligence in permitting the existence of a pen from which a wolf, doing what carnivores will, could bite someone on the viewing side of the enclosure. There was a verdict for the plaintiff. From the judgment on the verdict, the defendant has appealed.

1. The incident occurred in 1975. Accordingly, this case is governed by Vaughan v. Commonwealth, 377 Mass. 914 (1979), which held that settled common law principles concerning governmental immunity and exceptions to it would apply to claims against governmental bodies and their employees as to causes of action arising before August 16, 1977. On and after that date, events giving rise to a tort claim against the Commonwealth and its subdivisions (including municipalities) became controlled as to substance and procedure by G. L. c. 258, as appearing in St. 1978, c. 512, § 15. As to effective dates, see St. 1978, c. 512, § 16. See Lemasurier v. Pepperell, 10 Mass. App. Ct. 96, 98 (1980).

Although Whitney v. Worcester, 373 Mass. 208 (1977), expressed an intent, if the Legislature did not act, to abandon the misfeasance-nonfeasance distinction in suits against a public officer, the fact of subsequent legislative action gave continued life to the traditional principles regarding the immunity of a public officer which are restated at page 220 of the Whitney decision. Under the old rule, “[Pjublic officers engaged wholly in the performance of public duties are liable only for their own acts of misfeasance in connection with ministerial matters.” Id. at 220, quoting from Fulgoni v. Johnston, 302 Mass. 421, 423 (1939). Nonfeasance, the omission of an act which a person ought to do, creates no liability. Misfeasance is the improper doing of an act. Trum v. Paxton, 329 Mass. 434, 438 (1952). Whitney v. Worcester, 373 Mass. at 220. Compare the provisions which now appear in G. L. c. 258, § 10.

There was no evidence that the defendant had any direct role in the design, construction or maintenance of the wolf pen. He is not personally liable for mistakes which subordinates might have made. Trum v. Paxton, 329 Mass. at 438. Therefore, the motion for judgment notwithstanding the verdict should have been allowed. See O’Shaughnessy v. Besse, 7 Mass. App. Ct. 727, 728 (1979).

2. Although, on the view we take of the case, we need not reach the point, we note that the judge did not charge the jury on the misfeasance-nonfeasance distinction. The defendant’s counsel called this defect in the charge to the judge’s attention after the conclusion of the instructions to the jury. 1 The judge erred in refusing to amend his charge because the defendant had made no request for such an instruction prior to commencement of the charge. Although it is a good practice for a litigant to request certain instructions before the charge, it is not legally necessary to do so. Parties are entitled to an accurate statement of the law for the guidance of the jury. Hughes v. Whiting, 276 Mass. 76, 79 (1931). Smith & Zobel, Rules Practice § 51.3 (1977). Compare Narkin v. Springfield, 5 Mass. App. Ct. 489, 491-492 (1977). Parenthetically, we observe that the judge’s charge also did not mention contributory negligence, of which the evidence was redolent. We also note that upon concluding his charge the judge left the courtroom without affording counsel a chance to object to the charge. This conduct effectively nullified the right afforded counsel by Mass.R.Civ.P. 51(b), 365 Mass. 816 (1974), to object to instructions before the jury retires. The record reflects that defense counsel instantly took steps (counsel were ushered into the judge’s lobby within five minutes of the recess) to see the judge in his lobby for the purpose of making known the defendant’s objections.

Judgment is reversed and a new judgment shall be entered for the defendant.

So ordered.

Notes

Hedging his bets on whether Whitney announced a change in the law or just an intent to change the law, counsel also asked for — and was denied — an instruction on the ministerial-nonministerial duty distinction. See Whitney v. Worcester, 373 Mass. at 220-221. Compare G. L. c. 258, § 10.
