Because nationality acquired through naturalisation is not the same as nationality acquired through descent, members of the PSD proposed in 2009 another change in the law. This proposal would have given nationality by origin (descent) rather than by naturalisation to the grandchildren of Portuguese citizens but it was rejected. In 2013, members of the PSD tried to pass a similar measure again but due to the political and economic crisis that engulfed the country, no vote was ever taken on the measure.
