Three of the nine proposed amendments to the Texas Constitution on the Nov. 5 ballot face stronger arguments against them than the rest. Early voting starts Monday.Extensive discussions of the proposals are available on the House Research Organization website. Proposition 3Local governments may approve “freeport” areas where certain goods are exempt from inventory taxes if they are held for no longer than 175 days. Proposition 3 would allow that period to be stretched to 730 days (two years) for aircraft parts only.The change is in part an attempt to allow Irving to lure a second large warehouse contemplated by Aviall, a supplier of aircraft parts and support services.Some opponents complain that the amendment would lead to reduced tax revenue. Others say the inventory tax should be eliminated.It’s important that the proposal would allow, not require, local entities to extend the exemption. That should be a matter of local control.Proposition 7Texas cities with populations of more than 5,000 that have adopted a home-rule charter may have governing bodies with terms of office up to four years. Those with terms between two and four years must fill any vacancies by special election, which can be expensive.Proposition 7 would allow those cities with long terms of office to fill vacancies for unexpired terms of 12 months or less by appointment.Elections allow greater accountability, but cost is always a factor. For short terms, appointments make sense. Changes in city charters still require voter approval.Proposition 9The State Commission on Judicial Conduct investigates charges of misconduct by Texas judges. When the investigation involves formal hearings, the commission can issue an order of public censure or recommend that the judge retire or be removed.Proposition 9 would allow lesser penalties, including public admonition, warning, reprimand or a requirement for further training or education.Opponents say the current structure ensures that formal proceedings are used in only the most serious cases. But the change would allow more public information about investigations of judicial misconduct and the fairness and effectiveness of the inquiry.The Star-Telegram Editorial Board recommends votes for propositions 3, 7 and 9.
