Media freedom has deteriorated across the world over the past 15 years with populist leaders attacking journalism in both democratic and repressive states. Since the rise of online misinformation and disinformation, concern is growing that governments are using fake news language and related laws to muzzle the press. Studies find labelling reporters and their stories as fake news can threaten journalistic norms and practices and have implications for trust relationships with sources and audiences. Less understood is the effects of fake news laws on journalism. This article addresses this gap and examines consequences for journalistic practices in Singapore and Indonesia when journalists and sources are targets of fake news laws. Through 20 in-depth expert interviews with journalists, editors, their sources and fake news experts in Indonesia and Singapore, the article identifies "chill effects" on reporting when faced with the threat of new legal sanctions. However, it also identifies adaptations to newsroom practices to manage this threat. We conclude with lessons learned from the Asia Pacific on how journalists in other jurisdictions might manage the potential chilling effects on news reporting when fake news laws are in place.
