Raymond argued that pursuant to the case of Nguyen - Crawford v. Nguyen, 2010 ONSC 6836, when there were suspicious circumstances of undue influence surrounding
the execution of a power of attorney, the presumption of capacity is inoperative and the burden of proof regarding capacity shifts to the attorney.
According to previous case law
of the Constitutional Court, the right to a fair trial in the Spanish Constitution requires that, if a person has been convicted in his absence, a surrender for the
execution of that conviction must be made conditional on the right to challenge the conviction in order to safeguard that person's rights
of defence, even if he had given
power of attorney to a lawyer who effectively represented him at the trial (paras 20 and 22).
