Lawyers never lie. that would be unethical.
Instead, lawyers "speak colorably"; If one takes the pure white light of truth, and puts it through a prism, all of those colors in the spectrum of truth, while not 100% of the truth, still contain a very strong thread of it.
for example, I was in court recently settling a criminal charge for someone about two months ago, and that someone asked the crown prosecutor (during the hearing) why the crown has gone silent on the civil process settling the charges. The crown, unable to lie, or even acknowledge a commercial default, stated colorably that the paperwork was "not necessarily valid" in a criminal case. not only was this true, but this kept the prosecution in honor, the court in honor, and the defendant in honor, all while allowing him his "Section 11" remedy (canada criminal code).
I'd suggest using colorable language any time you feel the need to lie.
TL:DR - In the eyes of the law, telling a spectrum of truth is still considered telling the truth.
