The article tries hard to paint the picture that Queen pressurized in a uncouth manner the government to change the (proposed) legislation, but to me it seems the legislators were perfectly happy to accommodate the Queen without any significant pressurization. From my point of view just voicing opinion or preference (which I think happened here) should alone not be considered pressurization. If there was any threat, coercion, or bribery going on then the situation of course would be very different, but I cannot see it being the case here.
