Our conclusion is consistent with our established analytical approach to cases interpreting the quiet enjoyment statute. In Simon, supra at 101, and again in Cruz, supra at 789, we observed that the “Legislature may have contemplated a balance between tenant protection and the legitimate interests of landlords, and therefore may have intended that some degree of fault or foreseeability should be a prerequisite to liability under § 14.” We have also said that § 14 imposes liability whenever the “ ‘natural and probable consequence’ of a landlord’s action was interruption of the tenant’s rights.” Simon v. Solomon, supra at 102, quoting Westland Hous. Corp. v. Scott, 312 Mass. 375, 381 (1942). In Cruz, we observed that the landlord had notice of the defects in the leased premises which it failed to repair, and that it was “wholly foreseeable” that the injury to the tenant would result from this failure to make the repairs. Indeed, in each case since the 1973 statutory revision in which we have recognized a breach of the covenant of quiet enjoyment, there was evidence that the landlord failed to act reasonably in the circumstances concerning a problem known to the landlord, and the natural and probable consequences of such failure caused the interference with the tenant’s quiet enjoyment of the premises. See, e.g., Cruz, supra at 790; Doe v. New Bedford Hous. Auth., 417 Mass. 273, 285-288 (1994)7; Darmetko v. Boston Hous. Auth., 378 Mass. 758, 761 (1979).
