In a private complaint case, such as yours, if the complainant has appointed an advocate, the court will generally not insist on the personal attendance of the complainant except when it may be necessary. So, if your father, who is the complainant, has appointed an advocate to represent him and conduct the case, he should be in a position to get exemption from personal attendance, except when it is found to be necessary.
Living at a far-away place from the court becomes an additional ground to seek exemption from personal attendance, though it is not necessary that the court will always agree to dispense with the personal attendance on this ground alone.
Your father can make an application to the court for personal exemption.
