Gary Cowen's recent appearances in the Court of Appeal include a second appeal in an adverse possession claim and a claim for derogation of grant involving allowing plants to grow over a visibility splay at the end of a right of way. In the Chancery Division, Gary succeeded in persuading the Court that the true construction of a restrictive covenant prevented the owner of a landscaping strip from building a cycle track through it. Gary has also been advising in complex litigation concerning the validity of legal charges where the corporate mortgagor alleged that it had entered into the charges as a result of the undue influence of a third party. He has also continued to take on leasehold enfranchisement work including two appearances in the Lands Tribunal relating to deferment yield rates and the valuation of mooring rights in the LVT.
