Countries A and B are both WTO members. Country A has a strong organic free range egg industry but allows the production and sale of caged and non-organic chicken eggs. The egg industry in country A has publicly stated that it wishes to exclude competition in order to preserve jobs and has lobbied successfully the government of country A to place a prohibition on the import of eggs from caged and non-organic chicken from other countries. Country A has justified this ban - which goes beyond any international standard - by relying upon the expert opinion of Professor Eaglebottom who has proclaimed that eggs from caged and non-organic chicken have a one in 100,000 chance of producing cancer. Professor Eaglebottom's views have appeared in one peer reviewed journal but the vast majority of scientists in this field maintain that there is no health risk whatsoever from eating eggs from caged non-organic chicken. Country B wishes to export non-free range and non-organic eggs into country A's egg market. Required: Can country B successfully challenge country A's import ban under the WTO rules, discuss?
