About David Cheifetz

David Cheifetz was once a civil litigation litigator, first in Ontario and later in British Columbia, and also once an occasional author on legal topics; primarily on causation or contribution. His blog, "The 4th Monkey", at, is where you'll now (usually) find his (some might say) overly analytical musings. He retired from practice in early 2016 in order to "read law" for another graduate degree at Oxford. Why Oxford? At least because the gargoyles are better as is the weather.
