Pro bono publico – this term comes from Latin. It refers to the legal services performed by lawyers for people who are in need, or the services, performed by lawyers for social organizations. I.e. in these cases where a legal work is done in public benefit; in benefit of the society, and not just in interest of concrete private individuals.
* Note that practicing lawyers do not protect individual people for free (except where provided n th legislation), i.e. they don’t work and. accept pressure by the opposite parties for free; their personal advocacy is paid, so when asking a lawyer for their legal opinion on a concrete legal issue, you should pay them for their opinion and legal advice; it is the same like when you visit a doctor and pay for their competent diagnose and accurate medical treatment.
