Rory MullanOld Square Tax ChambersVery good written work, presents well, good bedside manner and nice to work with.

Most of the members at Old Square Tax Chambers have a heavy private client focus advising extensively on complex UK and offshore matters. James Kessler QC is advising a Greek shipowner whose domicile is being challenged by HMRC. In another highlight, Rory Mullan represented Tony Jimenez in the Court of Appeal in respect of a challenge to the HMRC’s decision to issue an information notice to him in Dubai. That decision has huge implications for the Revenue as regards the manner and means by which it carries out tax investigations. Permission to appeal has been granted by the Supreme Court. With rising stars Mary Ashley and Ross Birkbeck as juniors to watch, the future of chambers looks bright.
