Maine has become the latest state to take sides in the grudge match over whether it is ethical for lawyers to search electronic documents for metadata hidden beneath the bytes. Maine says no, joining New York (both the state and county bars), Florida, Alabama, and Arizona. The ABA (Formal Op. 06-442), Maryland, Colorado, and D.C. place the heavier burden on the party creating or sending the electronic document and permit recipient lawyers to search at will. Pennsylvania sort of punted.
