SURKHET/ JUMLA, Aug 21:  The number of cases have reduced significantly in courts after the government introduced the new civil and criminal codes four days ago to replace the centuries old Muluki Ain.   The cabinet had approved the code a year ago but it came into effect from Friday. A large number of government officials and locals are unaware about the act due to the lack of promotion and publicity. Until Monday, only seven cases were filed in the 10 districts of Karnali Province.
