Basically, the ruling by U.S. District Judge Ann Donnelly in New York temporarily halted the deportations of individuals detained in airports.
Donnelly [...] ruled in the Eastern District of New York that "there is imminent danger that, absent the stay of removal, there will be substantial and irreparable injury to refugees, visa-holders, and other individuals from nations subject" to Trump's order.
The ruling by U.S. District Judge James Robart in Seattle temporarily blocks Trump's travel ban altogether nationwide.
CBS News’ Paula Reid said the order, for the time being, effectively rescinds the Trump executive action, putting on hold the most controversial provisions of the law - including suspending entry of immigrants and nonimmigrants from the relevant counties; banning of refugees from certain countries; giving preference for some refugees based on religion; and banning of Syrian refugees.
So, in conclusion, the first court ruling halted the removal of individuals that have already arrived in the US while the latter suspended Trump's travel ban altogether.
