Kauffman v. TTC Case Mrs. Kauffman was exiting a TTC station. She was going up an escalator, and the escalator had metal hand rails, not rubber ones. Some young fellows ahead of her started to fight, and they tumbled down the escalator. The youths fell on top of a businessman, who in turn fell on Mrs. Kauffman. Poor Mrs. Kauffman was injured in the melee. Mrs. Kauffman sued the TTC. She argued that the TTC was negligent because : (a) its escalator did not have a rubber hand rail; (b) there wasn't a security guard supervising people entering and exiting the station.
