Ohio Code § 4909.13

§ 4909.13.

The public utilities commission may cause further hearings and investigations to be

had for the purpose of making revaluations or ascertaining the value of any betterments,

improvements, additions, or extensions made by any public utility or railroad subsequent

to any prior hearing or investigation, and may examine into all matters which may

change, modify, or affect any finding of fact previously made, and may at such time

make findings of fact supplementary to those previously made.  Such hearings shall be had upon the same notice and be conducted in the same manner,

and the findings so made shall have the same effect, as the original notice, hearing,

and findings.  Such findings made at supplemental hearings or investigations shall be considered

in connection with and as a part of the original findings except insofar as such supplemental

findings change or modify the findings made at the original hearing or investigation.
