This is an appeal from the grant of a judgment declaring that Kevin Ladd’s pri- or 120-day callback incarceration did not count as a prior commitment for the purpose of determining his mandatory minimum sentence under section 558.019, RSMo. The Appellants contend that the circuit court erred in giving retroactive *185effect to section 559.115.7, which precludes a 120-day callback from counting as a commitment for this purpose.
Having carefully considered the contentions on appeal, we find no grounds for reversing the decision. Publication of a formal opinion would not serve jurisprudential purposes or add to understanding of existing law. The judgment is affirmed. Rule 84.16(b).
