GEC spliced?

I don't have the 2011 NEC, just the 2008. Maryland uses the 2011. For what it's worth:

250.64 Grounding Electrode Conductor Installation

© Continuous. Grounding electrode conductor(s) shall be installed in one continuous length without a splice or joint except as permitted in (1) and (2):

(1) Splicing shall be permitted only by irreversible compression-type connectors listed as grounding and bonding equipment or by the exothermic welding process.

(2) Sections of busbars shall be permitted to be connected together to form a grounding electrode conductor.

What about the size difference?

It's wrong because there shouldn't be a wire nut splice at all, because the wire nut isn't listed for those two sizes of wire, because the smaller wire is too small to perform as a GEC, and because the smaller wire is too small for the lug that it lands on.

I find it hard to believe that a journeyman electrician did that work.
