    Received by the intake team

  2. 02 · Day 1 · Search

    The conflict search finds one hit.

    Every party is searched across matters, contacts, calls and mail. Daniel Kesh was a client of the firm in 2023, on a personal matter.

    AI: searched 6 parties, found 1 former-client hit and explained it.

  3. 03 · Day 2 · Decision

    The conflicts partner clears it, with a wall.

    Niamh Gallagher reviews the hit. The firm can act if the two lawyers from 2023 are kept outside the matter and cannot reach its files.

    Niamh Gallagher: cleared the matter on condition of an ethical wall.
