In this case we are faced with the issue whether to apply retroactively our holding in the case of
Mounsey
v.
Ellard,
The facts are as follows. The plaintiffs father is the brother of the female defendant. On the day of the accident, April 9, 1970, the plaintiffs and the defendants’ families were neighbors. About 9 a.m., on that date, by previous arrangement, the plaintiff’s mother drove him, age two and one-half, and his brother, Donald, almost four years of age, to the defendants’ home. The boys had been frequent visitors to the defendants’ home. The plaintiff’s mother was to drive one of the defendants’ children to an orthodontist in Acton since the female *47 defendant did not drive. The plaintiff’s presence with his mother was expected, and the children were to stay with the female defendant during this trip.
The male defendant was not at his home at the time of the plaintiff’s injuries. The male defendant had been in the process of remodeling the home since the summer of 1969. Off the kitchen, at the back of the house were sliding glass doors which had been installed during the summer of 1969. The sliding doors were to connect with an outdoor patio. Since the patio had not yet been built, there was approximately an eight-foot drop from the bottom of the sliding doors to the ground.
The sliding doors were customarily kept closed and, until approximately two days prior to the plaintiff’s injuries, a number of flower boxes had served as a barrier between the kitchen and the doors. This barrier had been removed by the female defendant. There were also screens available for placement beyond the sliding doors, but these were not in place at the time of the accident.
As the plaintiff entered the kitchen of the defendants’ home, he bumped his head on a projection, cried and was picked up and comforted by the female defendant. She then set him down, in the kitchen, about three feet from the sliding doors, which were open about one and one-half feet. There was evidence that the female defendant had opened the door a little earlier to respond to an emergency in the backyard involving one of her younger children who was climbing a tree. The female defendant then turned her attention to a rip in the clothing of the plaintiff’s mother, and left the room. The plaintiff’s older brother cried out in alarm, and their mother became aware of the open sliding door and the plaintiff’s disappearance. She ran outside and discovered the plaintiff lying face down on the ground below the sliding doors.
1. We turn first to the issue whether the male defendant owed a duty of ordinary care to the plaintiff. If the plaintiff was a social guest, under the old rule he *48 could recover only on proof of gross negligence, or wilful, wanton or reckless conduct. The declaration sounds in negligence, and it seems clear also that the evidence does not warrant an inference of gross negligence, if that proof is required.
The plaintiff argues, first, that it is not necessary to apply the
Mounsey
doctrine in the instant case, since he claims that the plaintiff’s visit to the defendants’ house was for their economic benefit. In support of this argument, he cites such cases as
Pope
v.
Willow Garages Inc.
The Mounsey case was decided on June 6, 1973. Its holding is best summed up by our words, “Therefore, we no longer follow the common law distinction between licensees and invitees and, instead, create a common duty of reasonable care which the occupier owes to all lawful visitors.” Id. at 707. We expressed no view in that opinion whether the doctrine should be applied retroactively or merely prospectively. The plaintiff here argues that we applied the new rule retroactively at least in favor of the plaintiff in the Mounsey case. He therefore urges that we should apply the new rule retroactively in all cases at least as far back as January 20, 1967, the date of the injury in the Mounsey case. (The accident in the instant case occurred on April 9, 1970.) We disagree with that proposition.
It is not unusual for an individual bringing an appeal in a challenge to existing law to obtain relief while others somewhat similarly situated are not afforded the benefit of retroactive application of the principles established by
*49
that first appellate determination. See, e.g.,
McIntyre
v.
Associates Financial Serv. Co. of Mass. Inc.
In now holding that the
Mounsey
rule is to be applied retroactively, we have no hesitancy in concluding that our decision will not in any serious way impair existing interests nor will any expectation be disappointed or any reliance be defeated. See
Diaz
v.
Eli Lilly & Co.
As we did in the Diaz case, supra, we declare further that where the claim for the physical injuries has been concluded by judgment or settlement or by the running of the statute of limitations prior to the rendering of this opinion, the Mounsey doctrine is not to be regarded as in any way benefiting or reviving a plaintiff’s action.
*50 Our holding as to retroactivity is not confined to cases involving social guests only, but applies to all cases involving plaintiffs who are entitled to ordinary care under the Mounsey rule.
2. Having determined that the defendants’ duty to the plaintiff is measured in terms of negligence, we must decide whether the evidence warranted an inference of negligence of the male defendant. Clearly it did. The presence of small children near the doors was a frequent occurrence, and this fact could be found to have been known to the male defendant; there was a drop of eight feet outside the doors; former barriers had been removed, and it could be found that the male defendant knew of this; the doors were easily unlatched and opened from the inside; it was reasonably foreseeable that some person would leave the doors open while small children were in the room.
Exceptions overruled.
Notes
The parties in their briefs and arguments assume correctly that the Mounsey case abolished the distinction between invitees and visitors, like the minor plaintiff here, whom this court has in many cases *46 characterized by the words “social guests” or similar terms. See the collected terminology in the concurring opinion of Quirico, J., in Mounsey v. Ellard, supra, at 714. The Mounsey case abolished the distinction between business invitees and all other entrants on the land, except trespassers. “ [We] create a common duty of reasonable care which the occupier owes to all lawful visitors.” Id. at 707.
The action was apparently commenced both in the names of the minor plaintiff and his father; the father’s counts for consequential damages were waived and the jury were instructed to include medical expenses in their verdict.
