A Voyage C/P provided that loading laytime was to cease from 1700 hours before until 0800 after a “public holiday”. Owners disputed the interruption of laytime at Paranagua for the “Corpus Christi” holiday on the grounds that it did not appear in the BIMCO calendar. The Tribunal found that the BIMCO calendar was not definitive on the point and accepted instead Charterers’ evidence (from the Brazilian Embassy in London website) that Corpus Christi was one of the public holidays observed throughout Brazil.
