Senior Counsel

The title of Senior Counsel or State Counsel (post-nominal letters: SC) is given to a senior lawyer in some countries that were formerly part of the British Empire. "Senior Counsel" is used in current or former Commonwealth countries or jurisdictions that have chosen to change the title "Queen's Counsel" to a name without monarchical connotations, sometimes (but not always) because the British monarch is no longer head of state, such that reference to the Queen is no longer appropriate. Examples of jurisdictions which have made the change because of the latter reason include Mauritius, Zambia, India, Hong Kong, the Republic of Ireland, South Africa, Kenya, Malawi, Singapore, Guyana and Trinidad and Tobago. Just as a junior counsel is "called to the [Outer] Bar", a Senior Counsel is, in some jurisdictions, said to be "called to the Inner Bar". Senior Counsel may informally style themselves as silks, like their British counterparts. This is the case in Ireland, Australia, Hong Kong and South Africa.

In Hong Kong, Senior Counsel (both men and women) must wear the black robe and silk gown together with a wig when appearing in open court.

In the Republic of Ireland, Senior Counsel wear a silk gown which differs from that of a Junior Counsel. The wig is optional in the Republic of Ireland.

The rank of Senior Counsel has also been introduced in most states and territories of Australia, even though the Queen remains head of state. Between 1993 and 2008 all Australian jurisdictions except the Northern Territory replaced the rank of Queen's Counsel with that of Senior Counsel. However, in 2013 Queensland restored the rank of Queen's Counsel and there was talk of other Australian states following suit. On 3 February 2014, the Victorian Attorney-General announced that the rank of Queen's Counsel would shortly be reinstated in Victoria, with existing and future Senior Counsel having the option to apply to be issued with letters patent appointing them as Queen's Counsel. The formal difference appears to be that QCs receive a warrant signed by the Head of State, the relevant State Governor - whereas SCs receive a certificate issued by the relevant Bar Association or bureaucracy such as by the judiciature of the State Supreme Court as the case may be.
