-3Factual Background 6. The respondents to this appeal were three teachers at the Church of Christ in China Heep Woh Primary School (the first three named respondents) and a teacher in another school (the fourth respondent) who had been a classmate of the second respondent. 7. Children could seek admission to the school, which was government subsidised, through an open admission process involving a competitive interview-based assessment. The first three respondents were among teachers at the school who were to conduct the open admission interviews on 14 June 2014. They were briefed on the day before the interview by the teacher in charge of the process for the 2014/2015 academic year. 8. Each of the teachers being briefed, including the three respondents, was provided with a plastic folder containing a copy of the Interview Questions and the Marking Scheme. The first and second respondents used their mobile phones to take photographs of the contents of the folders at the briefing and sent the photographs to third parties using WhatsApp. The first respondent sent the photographs to a friend in her church. The second respondent sent her photographs to the third respondent in the course of the briefing. The third respondent used a school computer to type up the interview questions into a Word document which was then sent by email on the school computer to the second respondent and, using her mobile phone, to a friend. The second respondent sent the Word document by email to the fourth respondent and a friend. The fourth respondent used her mobile phone to take photographs of the questions and transmitted them to two friends by WhatsApp.
