Something’s afoot in the field of the law, and in part it apparently has to do with something that happened in California on January 1, 2001. What was it? Further searching turns up this:
Thoughts on “shall” from Joe Kimble. If you want to discuss this with him, send him an e-mail [kimblej@cooley.edu]:
“Shall” has three strikes against it.
First, lawyers regularly misuse it to mean something other than “has a duty to.” It has become so corrupted by misuse that it has no firm meaning.
Second – and related to the first – it breeds litigation. There are 76 pages in “Words and Phrases” (a legal reference) that summarize hundreds of cases interpreting “shall.”
Third, nobody uses “shall” in common speech. It’s one more example of unnecessary lawyer talk. Nobody says, “You shall finish the project in a week.”
For all these reasons, “must” is a better choice, and the change has already started to take place. The new Federal Rules of Appellate Procedure, for instance, use “must,” not “shall.”
For a good discussion, see Bryan Garner, A Dictionary of Modern Legal Usage (2d ed. 1995), pages 939-942.
And this: 2004 California Rules of Court…Introductory Statement…Throughout the rules, “shall” and “must” are mandatory, “may” is permissive, and “should” indicates a nonbinding recommendation. “Will” indicates a future contingency or predicts action by a court or judicial officer in the ordinary course of events, but does not signify a mandatory duty. Whenever “must” is used in a new rule or an amendment to a rule with an effective date on or after January 1, 2001, it is synonymous with “shall” as used in the rules before that date… All of the California Rules of Court have the force of law.
And this: 2002The Introductory Statement is amended to reflect the recently adopted council policy on the use of must instead of shall. The amendment also clarifies that local rules declaring optional council forms to be mandatory are preempted by rule 981.1, and reinforces the distinction between forms adopted for mandatory use and those approved for optional use.
So, just as it is with a lot of other things, here it appears to be the lawyers’ fault, for misusing, abusing and corrupting a perfectly good and honorable word to the point that it no longer means to many what it should to all, ultimately forcing the rest of us to change.
Lawyers. California. Mighta known.
