The Secretary of State's Office postponed certification Friday of two petitions dealing with public school funding and a higher minimum wage.
Office spokesman Steve George said Storey and Pershing counties were unable to hand over their lists of verified signatures by the 5 p.m. deadline due to various reasons, including staffing issues.
The counties plan to deliver the signatures Tuesday, George said.
The initiatives call for Nevada schools to be funded at or above the national average and a raise in the minimum wage to $6.15 an hour from the current $5.15.
If certified, voters will have to approve the measures in November and again in 2006 before they take effect.
There's a July 9 deadline for other proposals dealing with marijuana, insurance rates and frivolous lawsuits.
Supporters of two other proposals, to reduce taxes approved by the 2003 Legislature and to keep public employees from serving in the Legislature, won a court order giving them until July 20 to turn in their signatures.
