Great read.

jbshack said;"The funniest part is people like yourself Dmitri say they are breaking the law, yet very rarely can anyone show were they have been charged or convicted of doing so. To be frank i know often they would prefer that they were taken to court. An example was when the "Save the tree alliance" jumped on board the Shona Maru two a few years back of Bunbury. They were never charged, one guy was arrested for outstanding fines but no charges. Sad because if they had been taken to court, they would have then shown that a Japanese Whaling vessel of only 10 miles of shore, well with in the 200 mile exclusion zone. So Japan would have been found to be illegally in Australian waters"
"So Japan would have been found to be illegally in Australian waters" - Under what law or jurisdiction would they be in breach of?
The Japanese were not indulging in fishing and the gear was correctly stowed, yes they were within Australia's 200 mile Exclusive Economic Zone, Fishing Zone or Continental Shelf so what were they doing that was illegal?
Under the UN's Maritime Charter.
Coastal States (Australia) exercise sovereignty over their territorial sea which they have the right to establish its breadth up to a limit not to exceed
12 nautical miles;
foreign vessels are allowed "innocent passage" through those waters;
Coastal States (Australia) have sovereign rights in a
200-nautical mile exclusive economic zone (EEZ) with respect to natural resources and certain economic activities, and exercise jurisdiction over marine science research and environmental protection;
All other States have freedom of navigation and overflight in the EEZ.
Coastal States (Australia) have
sovereign rights over the continental shelf (the national area of the seabed) for exploring and exploiting it; the shelf can extend at least 200 nautical miles from the shore, and more under specified circumstances.
All States enjoy the traditional freedoms of navigation.
So if the "Fishing" gear was NOT deployed and remained stowed away then the Japanese vessel was transiting from point A to point B and NOT engaged in fishing.
So what were they doing that was illegal?The tree huggers on the other hand illegally boarded a vessel conducting a lawful transit (this is known as Piracy in the South China Sea and around the Horn of Africa). The only reason it didn't go to court was $$$$$'s, the Captain and Crew of the Shona Maru would have been required in country to attend court (maybe for several days) and the tree hugging dropkicks would've copped a couple of hundred dollar fines and maybe had costs (that they couldn't pay) awarded against them, not exactly economically sound.
I find
"The funniest part is" people claiming illegality where none exists.
Don't get me wrong,
I abhor the practice of whaling 
be it by the Japanese or Norwegians targeting toothed or baleen whales in the Northern or Southern Hemispheres but IMHO it should not be left to a volunteer funded privateer organisation to make them stop.
Governments (World wide not just Australia) should be placing huge economic barriers in the way of these poachers so that it becomes no longer financially viable for them to continue.
There is absolutely no point in sending a warship down there, what can they do other than observe?
Sea Shepherd are a dedicated and loyal bunch of Pirates driven by good intentions (but the road to Hell is paved with good intentions) and on that they are to be congratulated, but they are vigilantes and show total disregard to the International Rules for the Prevention of Collision at Sea (IRPCS). If one of the Sea Shepherd or Japanese "Scientific Research"

vessels had been holed and sunk in the Southern Oceans due to the blatant disregarding of the IRPCS, resulting in loss of life or an environmental incident where several hundred (thousand) tons of heavy fuel oil was spilt, they would be facing more than just a fine.
