Man again you are going on the wrong track ... First makeup your mind, are you in favour of democracy or are you in favour of Islamic rule as both are contradictory ...Ultimately every ruler will have privilege to make laws whether democratic or dictator. If a dictator makes rules, its your luck. Whereas in democracy a rule is discussed in public, figuratively implemented and practiced before it is brought into the parliament, because people are convinced to do so. After elections and formation of government, that thing is literally and formally made a law. A dictator is void of this facility. He will bring a law that majority will resist resulting in bloodshed. Remember Prophet Muhammad peace be upon him had minimum bloodshed in the history of revolutions.
Now if you have an issue with a law passed in a democratic system by the people, the blame is not on democracy or the people but effort and ability of yours to convince the people otherwise.
Coming to Islamic laws mentioned in the holy Quran, certain laws were suspended by Umer R.A. There was no uproar in public upon this action of Hazrat Umer, because people were aware of the reasons upon which he suspended those laws. This ability to judge laws comes from education and awareness. Why should only few people have that knowledge and not everyone. Dedicated team of specialists of Islamic matters would rule and others would follow them blindly, there's no such concept in Islam that some people will have knowledge and they will rule. Knowledge has to be for everyone and it requires hard work.
Dmocracy gave people the right to make laws contradictory to Islam, for example Allah is announcing war on people involved in financial business but our democracy passed the law and made it halal both by elected people and by dictator Zia-ul-Haq ...
So if you need Islamic rule than power of people to make laws should be limited and within the boudries defined by Quran.
