Normally, the constitution of Montana must grant equality of treatment for all people so for gays and lesbians also. Based on this, ACLU will defend Mary Anne Guggenheim and her partner of 27 years, Jan Donaldson.
Recently, Mary Anne undergo a surgery to replace her hip and the doctor refused to speak to Jan.
As Jan say it very well, "this case is about treating people fairly and humanely."
"We just want the dignity of having our committed partnership recognized as worthy of those legal protections."
ACLU said that the recognition of same-sex partnerships is necessary to confirm to uphold fair treatment for all, guaranteed by Montana's constitution.
"Anyone who works and pays taxes should be treated equally and fairly by our state," said Jennifer Giuttari, interim legal director for the ACLU of Montana.
"When two people are in a committed relationship, they should be eligible for benefits, like filing a joint tax return, regardless of whether they are a same-sex couple or a different-sex couple," she added.
