Nearly three decades ago, California enacted Proposition 13, a highly debated piece of legislation that limited property taxes to 1 percent of the full value of the property, and reduced them statewide by an average of 57 percent.Today, a swelling number of grassroots movements in several states that are protesting skyrocketing property taxes and filing appeals may usher in the question of whether the U.S. will one day need similar legislation on a national level.

Teleflex, decided on April 30, 2007, overturned a decision of the U.S. Court of Appeals for the Federal Circuit and found a patent claim invalid. In doing so, the high court also criticized the Federal Circuit for applying the wrong standard on patent claims and being too liberal in upholding patent claims for obvious improvements.

Sen. Chuck Grassley, R-Iowa, ranking member of the Senate Finance Committee, has sent a letter to his chamber colleagues in an attempt to blunt what he termed "inaccurate claims" about the private collectors employed by the Internal Revenue Service.In a "Dear Colleague" letter, Grassley pointed out that the agency's own collection infrastructure is better set up for placing liens and garnishing wages than it is for making initial phone calls to delinquent taxpayers to set up a payment plan.

Nexus - the amount of contact between a taxpayer and the state that subjects the taxpayer to taxation - continues to vary widely from state to state. In addition, the nexus for sales and use tax differs from the nexus for income tax.The nexus requirement is derived from the language in two different places in the Constitution - the commerce clause, which prohibits states from unduly burdening interstate commerce, and the due process clause, which requires a minimum connection between a state and an entity it seeks to tax.

Just in time for the summer, the U.S. Tax Court denied the like-kind exchange treatment for vacation homes that are not strictly held for investment purposes.In a memo issued Wednesday, the court said that a Georgia couple's exchange of vacation homes did not qualify for the treatment according to Section 1031(a) of the tax code -- finding that the holding of any residence, even if motivated in part by an expectation that the property will appreciate in value, is insufficient to justify the classification of that property as being held for investment.
