Australian steel-product manufacturer BlueScope Steel is embroiled in two court cases brought by the country\u2019s competition regulator. The company\u2019s former manager Jason Ellis is involved in both cases --- alleged attempted cartel conduct and criminal obstruction charges. Obstruction charges are often used in the US to aid cartel probes, but it\u2019s the first time the measures have been used in Australia in this context. Australasian Managing Editor James Panichi and Senior Correspondent Laurel Henning discuss what Australia could learn from the US when it comes to obstruction charges.
