case could have been transferred to Dublin if the majority of witnesses and experts are in Dublin. if you are against Govt Dept, then it would seem that as all witnesses are in Dublin, case is better set down there.
Having said that, your solicitor could/should have objected or sought priority on the transfer. If you are in poor health and if you feel that they are waiting for you to die so that the case won't come on, they you should have your solicitor apply for priority. if you are terminally ill, you will get priority.
