How this case was judged

Every CAUGHT case is assessed on three independent questions, and the weakest of the three decides. A case reads CAUGHT only when all three are established and a person has reviewed it.

• Activity unknown

  Was it fishing, here, and then?

  • Radar detection with no vessel attribution — establishes that a hull was present, not who or what it was.
  • No vessel was matched to this detection when it was raised, so there is no identity to research: a radar return carries no name, no MMSI and no registration. A closure cannot be enforced against a position.
  • What would settle it: an AIS track placing a named vessel at this position and time. Absent that, this case can never name a defendant and cannot be promoted.

• Vessel unknown

  What gear does this boat actually use?

  • No vessel identity on this case.
  • Every gear and licence record we hold is keyed on MMSI, so with no identity there is no record to find and no research that could produce one.

• Rule strong

  What was prohibited there, then, for that gear?

  • No-take closure: all fishing is prohibited, with no conditions in the rule text.

Not established: activity; vessel. A case is only as strong as its weakest factor, so this one cannot read CAUGHT until that is settled.
