Tributes For Retiring Lord Gill
Scotland's most senior judge has announced his intention to retire following the longest judicial career in Scottish history.
Lord Brian Gill, 73, will retire on May 31 concluding a legal career spanning 48 years in which he has served 21 years as a judge.
The Judicial Office for Scotland said: "In the course of a distinguished legal career he has presided over some of the most significant changes to the Scottish legal system in over a century, in particular the implementation of the proposals of the Scottish Civil Courts Review, which he led, as well as some major changes to criminal appeal procedure which are in the process of being implemented.
"The First Minister will now establish a panel to recommend individuals who are suitable for appointment to fill the vacancy.''
James Wolffe, QC, dean of the Faculty of Advocates, said: ``Lord Gill's career has been one of outstanding service to Scotland's legal system.
"At the bar, he was an incisive advocate in great demand. A learned Keeper of the Advocates Library, he authored the leading textbook on agricultural law.
"During his career as a judge, he has contributed greatly to the development of the law in judgments characterised by lucid prose and clarity of analysis.''
He added: "Although Lord Gill has announced his retirement, he has not yet quite retired. At this moment, I pay tribute to all that he has done so far for the law in Scotland and I wish him a long and happy retirement when that day arrives.''
Alistair Morris, president of the Law Society of Scotland, said: "The Lord President has been a much respected figure throughout his highly distinguished legal career.
"He has long been committed to reform and the modernisation of Scotland's justice system.
"Under his leadership the Scottish Civil Courts Review resulted in far-reaching proposals for change and he leaves an important and lasting legacy when he retires at the end of this month.
"The timetable for civil justice reforms, set out by the Lord President in January this year, will transform our civil courts.
"Better use of technology, improved administration systems and greater judicial specialisation will make our courts more efficient, more accessible for court users and will help improve access to justice.
"We have had a very constructive working relationship with the Lord President during his time in office and on behalf of the Law Society of Scotland, I wish him well for his retirement.''
