The Computer and Cybercrimes Bill, 2016 Expedited preservation and partial disclosure of traffic data. 25. (1) Where a police officer or an authorised person has reasonable grounds to believe that— (a) any specified traffic data stored in any computer system or computer data storage medium or by means of a computer system is reasonably required for the purposes of a criminal investigation; and (b) there is a risk or vulnerability that the traffic data may be modified, lost, destroyed or rendered inaccessible, the police officer or an authorised person shall serve a notice on the person who is in possession or control of the computer system, requiring the person to— (i) undertake expeditious preservation of such available traffic data regardless of whether one or more service providers were involved in the transmission of that communication; or (ii) disclose sufficient traffic data concerning any communication in order to identify the service providers and the path through which communication was transmitted. (2) The data specified in the notice shall be preserved and its integrity shall be maintained for a period not exceeding the period specified in the notice. (3) The period of preservation and maintenance of integrity may be extended for a period exceeding thirty days if, on an application by the police officer or authorised person, the court is satisfied that— (a) an extension of preservation is reasonably required for the purposes of an investigation or prosecution; (b) there is a risk or vulnerability that the traffic data may be modified, lost, destroyed or rendered inaccessible; and (c) the cost of the preservation is not overly burdensome on the person in control of the computer system. 23
