Grading rubric
Criteria and grader verdict (showcase run)
States that BlueLNG cannot obtain Rule B attachments for the wire transfer
PassEvidence: The response states, “For the stated shipbuilding-contract suit: **No Rule B attachment—neither the Obun wire nor the Maersk shares**” and specifically, “**US$ wire from Nakamura to Obun Corp.: likely no.**” Assessment: The criterion asks whether it states BlueLNG cannot obtain Rule B attachment for the wire transfer. Pass; the response clearly says no attachment is available for the wire under the stated claim, and also no even assuming a separate maritime claim for an EFT/payment to Obun.
States that BlueLNG cannot obtain Rule B attachments for the shares in the Southern District of New York
PassEvidence: The response’s bottom line says, “For the stated shipbuilding-contract suit: **No Rule B attachment—neither the Obun wire nor the Maersk shares—because the underlying claim is likely non-maritime.**” Assessment: The criterion asks whether it states BlueLNG cannot obtain Rule B attachments for the shares in the Southern District of New York. Pass; although it adds a hypothetical that shares might be attachable if there were a separate maritime claim, for the actual shipbuilding-contract suit it clearly states the Maersk shares cannot be attached under Rule B.
