a leg to stand on Viable proof or justification; something on which to base one’s claims or attitudes. A leg pro vides support and helps to maintain balance. Figuratively this expression is most often heard in the negative not have a leg to stand on, referring to one who fails to support his attitudes or behavior. It is frequently used in legal contexts where an inability to provide proof or justification is pronounced. The still current expression dates from the 16th century.
