In this artist's impression supplied by the ESO (European Southern Observatory) on April 25, 2007, the planetary system around the red dwarf, Gliese 581, is pictured showing what astronomers believe is the most earth like planet found outside our solar system to date. Using the ESO 3.6-m telescope in Chile, astronomers have uncovered the planet which could have water running on its surface. The planet orbits the faint star Gliese 581, which is 20.5 light-years away in the constellation Libra. (Photo by ESO via Getty Images)

Kiritimati is a far-flung outpost of the Republic of Kiribati. The world's largest coral atoll, Kiritimati has just one flight a week to either Fiji or Hawaii, four-and-a-half hours in either direction. Tarawa, the capital of Kiribati lies nearly 3,300 km (2,000 miles) to the west – about three weeks by boat. No lawyers are based on Kiritimati and the High Court only comes once or twice a year to clear a backlog of the most serious cases, bringing a public lawyer for defendants who can't afford their own.
