Validity

 

hold water To be valid, sound, and defensible; to show no inconsistency or deficiency when put to the test. As early as the beginning of the 17th century, this expression was used figuratively of arguments, statements, etc., although both hold and water can be taken literally to describe a vessel or other receptacle’s soundness in retaining a liquid.

Let them produce a more rational account of any other opinion, that will hold water … better than this mine doth. (John French, The York-shire Spaw, 1652)

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.

She hasn’t a leg to stand on in the case. He’s divorcing her, she’s not divorcing him. (M. Spark, Bachelors, 1960)
