Now, remember the case-law which states that an 'attorney' which uses a facsimile signature can't show that they acting as an attorney reviewed the file and as an attorney believes that they have a case which they could take to court; since a letter on a lawyers stationary is an implicit threat of legal action. How about 100% automated phone calls from a CAA? Again there is the threat of legal action because it is a 'law office' which is calling; and similarly the automated nature of the call shows that there is no attorney involvement with the making of the call. Is there any case-law regarding CAAs and automated calling messages?
Well, it's almost a mute point... The letter from the 'attorney' didn't even have a facsimile signature. So, they'll have fun arguing that a lawyer reviewed the account before they authorized the phone call, or the sending of the letter.
