Maritime National Fish v Ocean Trawlers [1935]

Plaintiffs chartered trawler from defendants.
Trawler could only be used with otter trawl, which required
licence.
Defendant had five trawlers but only three licences.
Did not give one to trawler in question.
Contract frustrated?
Privy Council held frustration resulted from charterer’s
deliberate act.
Could not rely on this self-induced frustration.
