Anbiguous use of language repeatedly leads to lawsuits, such as O’Connor v. Oakhurst Dairy over an Oxford comma, or Pulsifer v. United States over logical operators.

Will any country conduct an official government project (commission, grant, any form counts) with a primary stated goal of looking for such issues in existing law and correcting them?

Not sure how to quantify "large-scale", maybe something like minimum 50 separate changes made?

Feel free to add countries
