I want to know the answer to the following question:
In contrast to its acceptance of responsibility for keeping the pipelines new, Shell has denied what?
All the background I'm provided with is that "In January 2013, a Dutch court rejected four out of five allegations brought against the firm over oil pollution in the Niger Delta but found a subsidiary guilty of one case of pollution, ordering compensation to be paid to a Nigerian farmer.". Is that enough to answer the question?
Answer: no
