For example, You msg and take part in a conversation in a very small closed "group" of 3 people in WhatsApp, that you assume will always be private. You are person no 3. After which, one member of that group then physically shows the msgs to others , not in the group or ever intended to be privvy to such discussions as discussed in the group.
Can an author of a Whatsapp msg, reasonably expect that msgs sent to a closed Whatsapp group, remain private and if so , are there any legal recourses available to the author , if that reasonable expectation has been broken?
