The case for and against Japan’s ‘scientific’ whaling program

Final arguments from the defence and prosecution were heard in mid-July, and the world court is now considering its judgment. At issue is Japan’s right to conduct its seasonal “scientific” whaling program in Antarctic waters. But the case has been largely based around arguments about how to define science itself.

The legal challenge to Japan has been brought to the International Court of Justice (ICJ) in the Hague by Australia, which has asked the Netherlands-based court to find that Japan’s whaling program is illegal because it is actually commercial whaling — not scientific research that is permissable under the 1982 moratorium on commercial whaling declared by the International Whaling Commission (IWC), which went into effect in the 1985/86 coastal and pelagic hunting seasons.

On June 1, 2010, Australia initiated proceedings at the ICJ against Japan, alleging breach of international obligations concerning whaling.

Japan contends that Australia has embarked on an “alarmist crusade” against whaling.

The stakes are high. Political relations between Japan and Australia have been strained during the trial, with Japan accusing Australia of “an affront to the dignity of a nation” in bringing charges of lying about its whaling program.

But in the Southern Ocean the stakes for thousands of Minke whales, in particular, are higher. If Japan wins the case — and some commentators suggest it is in a strong position — the legal status of its whaling program could be strengthened.

Masayuki Komatsu, Japan’s chief whaling negotiator from 1999 to 2004, told The Australian newspaper that the international court could rule that Japan’s “scientific” whaling program — which many countries as well as Australia believe is a masquerade for a commercial whaling operation — is legitimate.

The worst-case scenario, for opponents of whaling, is that the court overturns the IWC’s 1985/86 moratorium on commercial whaling, known as Article 10E in the International Convention for the Regulation of Whaling. That outcome would be disastrous for whales worldwide — and it is precisely why the legal challenge to Japan, which at first glance many people opposed to whaling would probably support, is highly risky.

Japan’s legal team in the Hague also feels that the law is on its side. Noriyuki Shikata, a spokesman for the Japanese delegation, was critical about Australia’s legal arguments in court. In the closing submissions last month, Shikata said: “We have not really heard effective legal rebuttal based on evidence and reasoning and we have an impression that many of the allegations are driven by emotions, not science.”

Allan Boyle, a professor of public international law at the University of Edinburgh, made the claim that if Japan’s current whaling program was not scientific, then neither were the research activities of numerous institutions worldwide that use fisheries data to assess sustainable catch levels.

Another British legal expert, Vaughn Lowe, an emeritus law professor from the University of Oxford, said that “there is no uniquely correct formula” for what qualifies as scientific research. He said Japan’s view of its whaling program was that it is “an absurd exaggeration to say that it is not scientific research at all.”

The stated scientific objectives for  Japan’s  whaling program is that it needs to kill whales in order to understand the feeding ecology and population makeup of various whale species. With this information the country will be able to  “manage” whale numbers through hunting.

It is true that by catching and killing whales, and analyzing their stomach contents, a lot can be learned about cetacean biology. In the past, it was the only real method available to investigate these animals. But for many years now, it has been unnecessary to kill whales in order to get the information that Japan’s Institute for Cetacean Research says it needs.

That institute, which operates under the auspices of the Japan Fisheries Agency, a division of the Ministry of Agriculture, Forestry and Fisheries, which issues annual catch quotas. In line with those quotas, between 1988 through the first half of 2011, 13,663 whales were caught under Japan’s moratorium exemption for scientific research. Of those, 3,573 whales were taken in the North Pacific Ocean and 10,090 in the Southern Ocean, including from a large area designated by the IWC in 1994 as the Southern Ocean Whale Sanctuary.

The Australian case argues that all the data that Japan wants to collect can currently be done through methods that do not involve killing whales. Collecting whale faeces may not be the most pleasant job in the world, but analyzing the DNA found in them can tell scientists — without cutting open a whale’s stomach — what animals a whale has been eating.

Meanwhile, DNA samples can be taken with relative ease by removing only a small plug of skin . And a lot can be learned from their nasal mucus. Researchers can sample a whale’s breath by catching the gunk that spurts from its blowhole. (this can be ingeniously done by  flying remote-controlled helicopters over breaching whales, catching flying mucus on Petri dishes strapped to the sides of the choppers.) From these samples, scientists can determine the viruses, fungi and bacteria that live in whales’ lungs.

Killing whales provides negligible data to science. Less than 1 percent of the papers published on cetacean biology come from studies that required the killing of a whale.

In fact, tagging live whales tells you far more. GPS tags allow biologists to track whales and learn migration routes as well as daily routines. And acoustic tags record marine noise, so we can get an aural picture of the undersea soundscape — and an idea of the amount of noise pollution from boats that whales are having to tolerate.

Japan’s claims that it requires lethal whaling to conduct scientific research do not stand up. However, the case will be decided on the strength of the legal arguments that both countries put forward therefore the outcome may favor Japan and not the whales.
