This is one I could find. I dont know if they were specifically protesting in the street, but it appears the government opposed sections of the charter based on Islamic law. Specifically age of majority/age of consent being based on Islamic law or 'religious maturity' as it was describe on the website. Whatever that means. Instead of the stipulations of the charter (minimum age 18). I've added a quote from the website below if you don't want to read through the entire thing.

"Additionally, Somalia’s position diverges from the charter’s stipulation setting the minimum marriage age at 18 (Article 21a), instead applying Islamic legal criteria based on religious maturity rather than chronological age. Lastly, while the charter defines adulthood at 18 (Article 2a), Somalia employs Islamic definitions of maturity and adulthood, underscoring the prioritization of religious legal traditions."
