Morrison Waite,
Laughlin v. District of Columbia…
“ Such being the law, the only question we have now to consider is whether the letter of June 5, 1874, addressed by the attorney of Laughlin to the treasurer of the board of public works, and placed on file with the papers of the board, makes the District answerable to Laughlin for the amount due on the certificates, notwithstanding the payment to Cowdrey upon the allowance by the board of audit. ”
