Proximate Cause Can Not Be Based Upon Speculation; Many Possible Causes

In affirming the grant of summary judgment to the defendant, the Second Department explained that, although proximate cause can be established by circumstantial evidence, it cannot be based on speculation:

“Proximate cause may be established without direct evidence of causation, by inference from the circumstances of the accident; however, mere speculation as to the cause of an accident, when there could have been many possible causes, is fatal to a cause of action”.. . Belousov v Warnock, 2013 NY Slip Op 05787, 2nd Dept 9-11-13
