 In late 1903, Vyacheslav von Plehve, Minister of the Interior, asked Jaunius' expert opinion on whether the Cyrillic script was suited for the Lithuanian language (publication of Lithuanian texts in the Latin alphabet was banned since 1864).According to memoirs of Pranciškus Būčys, Jaunius delayed his response and insisted on correcting, rewriting, and reediting the response multiple times – Būčys had to rewrite the letter several times and mail it out before Jaunius could point out any further corrections.His reply that the Lithuanian language used a Latin–Lithuanian alphabet (and not Latin–Polish) was added the case file during government debates that led to the lifting of the ban in early 1904.
