construction of a drain originally sufficient, constructed other
drains discharging into it, which SO increased the flow of water that it was no longer sufficient.
The judgment under appeal is not, therefore, supported by this decision. No other authority has been cited in support of the argument that when a work authorized by Statute is carried out by a public body without negligence either in design or execu- tion, it can become actionable as against the constructors by reason of subsequent events over which they have no control.
Such a contention is, indeed, negatived both by principle and authority. When a public body undertakes in the exercise of statutory powers to construct a work of public utility, it is bound to use reasonable care both as to design and execution, and if from want of such care injury is caused to an individual he can maintain an action for damages. But in the absence of such negligence the construction of the work is a lawful act, which cannot afterwards become unlawful as against the constructors except by reason of their own subsequent unlawful acts or omis- sions. They are not liable for mere inaction, or, as it is called, non-feasance, unless the legislature has imposed upon them the duty of action. The remedy, if any, in such a case is to be found in the Statute which authorized the work. If none is to be found there, the persons injuriously affected have no cause of action, whatever other means may be open to them of obtaining redress Hammersmith and City Railway Co. v. Brand 1 Raleigh Corporation v. Williams 2.
If, therefore, there were no more in the case, the appellants would be entitled to judgment. But the learned Judge also found that in 1910 the outlet of the drain was very seriously obstructed by a compacted mass of material, which, according to the evidence, diminished the capacity of the outlet by about one- half. He did not make any express finding as to the existence of this obstruction at the times when the floodings complained of occurred. But upon the evidence there was reason to believe that the accumulation of the mass had been going on for some years, and it appeared that the defendants' officers had since 1905, when a complaint was first made on the subject, given
