 Today the concept is so widely accepted that there is a general presumption that there should be judicial openness, such that openness is the rule, with secret or obscured proceedings being considered as exceptions needing to be justified.The rise of social media websites such as Facebook has opened new ways for court cases to be made public; for example, in Australia, courts have considered having websites with live videos as well as blogs by retired judges to "preserve the concepts of open justice" in the digital age.In recent years, when governments try to cope with thorny problems such as terrorism, there are concerns that the principle of open justice can be undermined relatively easily by national security concerns.
