example*?
laws have developed due to changing views of society e.g. homosexuality
use the Toonen Case as an example..laws overturned in NT.
Also Hope and Brown v. NIB health funds ltd, gave homosexual couple recognition as a family for insurance for the two of them and a child. These cases reflect society's chaning and more accepting view of homosexuals.
Or another example u could use is technology. Technology laws need to be developed to reflect peoples views on child porn and hacking etc to protect people. thats easy to exapand on for that point
hope that helped.
