This is an unwise decision, for reasons noted many times on this blog.  In some ways, however, it makes little practical difference; Nebraska had executed a grand total of three convicts in the last fifty years.  In that sense, the legislature abolished what was barely there anyway.

Still, the decision has moral consequence  --  so much so that, in my view, the voters should pass on it themselves, as Oregon voters did in both the general elections of 1978 and again in 1984 (the latter to effectively overrule a state Supreme Court decision that invalidated the state's death penalty statute).  The people of California also voted to retain the death penalty in the 2012 election, despite its costs and a well-financed (and deceptive) campaign against it.

The voters should have the last say, and I hope Nebraska law provides them a way to get it.

[UPDATE:  Nebraska citizens do, in fact, have the ability to repeal the death penalty abolition bill by referendum].
