Outline
An introduction to the engineering profession, including:
Standards and safety
Law: Charter of Rights and Freedoms, contracts, torts, negligent malpractice, forms of carrying on business
Intellectual property (patents, trade marks, copyrights and industrial designs)
Professional practice
Professional Engineers Act
Professional misconduct and sexual harassment
Alternative dispute resolution
Labour Relations and Employment Law
Environmental Law

3. Vicarious Liability
Employee Performance
Suppose an employee is negligent and someone is harmed as a result
Who is responsible for the tort?

4. Vicarious Liability
Inspections
Consider the case of Dutton v Bognor Regis United Building Co. Ltd., 1972
A house was built on a rubbish deposit
This will result in settling, but this can be dealt with through larger foundations
By-laws required that the foundation be approved by a building inspector
The inspector failed to make an proper inspection
Part of the building collapsed

5. Vicarious Liability
Inspections
In Dutton v Bognor Regis United Building Co. Ltd., 1972, the court found
The inspector was responsible
The local building authority, however, was liable for the damages

6. Vicarious Liability
Inspections
In Dutton v Bognor Regis United Building Co. Ltd., 1972, the court found
“It is at this point that I must draw a distinction between the several categories of professional men. I can well see that in the case of a professional man who gives advice on financial or property matters—such as a banker, a lawyer or an accountant—his duty is only to those who rely on him and suffer financial loss in consequence. But in the case of a professional man who gives advice on the safety of buildings, or machines, or material, his duty is to all those who may suffer injury in case his advice is bad.”

7. Vicarious Liability
Inspections
In Dutton v Bognor Regis United Building Co. Ltd., 1972, the court found
“If [an engineer] designs a house or a bridge so negligently that it falls down, he is liable to everyone of those who are injured in the fall: see Clay v A.J. Crump & Sons Ltd. None of those injured would have relied on the architect or the engineer. None of them would have known whether an architect or engineer was employed or not. But beyond doubt, the architect and engineer would be liable. The reason is not because those injured relied on him, but because he knew, or ought to have known, that such persons might be injured if he did his work badly.”

8. Vicarious Liability
Inspections
In Dutton v Bognor Regis United Building Co. Ltd., 1972, the court determined the council would bear the loss:
“First, Mrs. Dutton has suffered a grievous loss. The house fell down without any fault of hers. She is in no position herself to bear the loss. Who ought in justice to bear it? I should think those who were responsible. Who are they? In the first place, the builder was responsible. It was he who lid the foundations so badly that the house fell down. In the second place, the council’s inspector was responsible. It was his job to examine the foundations to see if they would take the load of the house. He failed to do it properly. In the third, the council should answer for his failure. They were entrusted by Parliament with the task of seeing that houses were built properly. They received public funds for the purpose... Their shoulders are broad enough to bear the loss.”

9. Vicarious Liability
Vicarious Liability
Vicarious liability is the doctrine that an employer is liable for the negligent performance of an employee Therefore, if an employee in his or her role has a duty of care to another party and that employee breaches that duty of care, the employer will be vicariously liable for any damages

10. Vicarious Liability
Vicarious Liability
The overriding point is that the injured party should be compensated for the harm, and the employer is most suited to ensure this occurs Consequently, any engineers employing others should obtain adequate professional insurance

11. Vicarious Liability
Employee Liability
Employees, however, can also be liable in tort, as in Northwestern Mutual Insurance Co. v J.T.O’Bryan & Co., 1974, where:
An insurance company asked the agent O’Bryan to remove an unused warehouse that had already been vandalized from a policy, a request that is standard in the industry
The first request by letter was dated January 12th, 1970
After two letters followed by two weeks of telephone calls, finally, an employee of the agent assured Northwestern that the risk would be removed and later was removed

12. Vicarious Liability
Employee Liability
Employees, however, can also be liable in tort, as in Northwestern Mutual Insurance Co. v J.T.O’Bryan & Co., 1974, where:
Had the employee said nothing, or had the employee given a disclaimer, Northwestern would have simply cancelled the policy themselves
Northwestern was required to pay $ when the warehouse was damaged by arson on July 13th
Northwest claimed breach of contract with O’Bryan and negligence on the part of both O’Bryan and the employee

13. Vicarious Liability
Employee Liability
In Northwestern Mutual Insurance Co. v J.T.O’Bryan & Co., 1974, the court found:
The employee was found to owe a duty of care to Northwestern for “inexcusable negligence”
The breach of this duty of care was the cause of the damage
The employer was held vicariously liable
Had the employee not been found guilty of tort, Northwestern could sue for only a breach of contract—a contract that likely had limitation clauses that would not allow Northwestern to recover all of its losses

14. Vicarious Liability
Employee Liability
In the case of Edgeworth Construction Ltd. v N.D. Lea & Associates Ltd., 1993, the plaintiff also claimed that the engineers who sealed the documents owed a duty of care
By sealing the documents, that establishes a duty of care on any who rely on that document
This would not make them directly liable, but rather, the liability would thus be spread between three parties: the contractor for not doing due diligence, the engineering firm, and its employees, and by vicarious liability, the engineering firm would be responsible for any negligence on the part of its employees

15. Vicarious Liability
Employee Liability
In the case of Edgeworth Construction Ltd. v N.D. Lea & Associates Ltd., 1993, the court found the seal does not establish a duty of care:
“The only basis upon which [the engineers] are sued is the fact that each of them affixed his seal to the design documents. In my view, this is insufficient to establish a duty of care between the individual engineers and [Edgeworth Construction]. The seal attests that a qualified engineer prepared the drawing. It is not a guarantee of accuracy. The affixation of a seal, without more, is insufficient to found liability for negligent misrepresentation.”
