SLAPP does not only occur in the environmental sector but in any situation which act aims to stop or eliminate public participation in aggression against certain policies. In the environmental sector, it is referred to as Eco-SLAPP which aims to provide fear, silence, and intimidation toward people who commit aggression against environmental policies and/or certain interests through reporting/complaints or lawsuits to court. Therefore, the Anti-Eco-SLAPP concept in Law Number 32 of 2009 was raised to provide protection against the act of Eco-SLAPP since it harms people who fight for good and healthy environment. Unfortunately, weakness is found in Law Number 32 of 2009 regarding substance and process in fulfilling Anti Eco-SLAPP. In terms of substance, Article 2 letter a Law Number 32 of 2009 has not given the state responsibility to implement Anti Eco-SLAPP, Article 66 Law Number 32 of 2009 has not regulated good faith as the reason a person cannot be prosecuted criminally or sued civilly, protection from administrative action, and motion strike/dismissal process and SLAPP Back, to prevent early Eco-SLAPP actions. In addition, the implementation of Anti Eco-SLAPP is often misinterpreted since it is unable to distinguish pure criminal acts and actions to fight for the environment based on good faith. Based on this, it is necessary to construct an Anti Eco-SLAPP law based on the weaknesses of the existing Law Number 32 of 2009, so as to reinforce the implementation of Anti Eco-SLAPP in Indonesia.
