. . . but MS Word did not:

Gmail flagged this error:

. . . but MS Word missed it.

It must be very uncommon for attorneys to review briefs in anything other than MS Word. Check a brief that you've been asked to cite check in Google Docs, and it may help you find some typos that the lawyers have missed.
